    Modifications to an expert report are allowed as long as there are no additions or substantive changes whatsoever; Court limits the testimony of both parties’ experts regarding the customs brokerage industry 

    This case involves a dispute between JAS Supply, Inc. (“Plaintiff”) and Radiant Customs Services, Inc. and Radiant Global Logistics, Inc. (“Defendants”) regarding the importation of alcohol wipes from foreign manufacturers. In 2020, Plaintiff contracted with Defendants to assist with importing alcohol wipes into the United States for the first time. Defendant Radiant Global Logistics provided freight forwarding services, while its related company Radiant Customs Services provided customs broker services to ensure compliance with customs regulations.  

    Plaintiff successfully imported 15 of 19 containers, but the final 4 were detained and eventually refused by U.S. Customs and Border Protection (“CBP”) due to missing information required by the FDA about the originating manufacturer. Plaintiff alleged that Defendants’ misconduct led to the damages from the refused products. Both sides retained experts on importation and customs brokerage industries – Plaintiff retained Kelli R. Thompson and Defendants retained Cameron W. Roberts. The parties filed motions to exclude each other’s expert testimony.

He is recognized as an expert witness in both State and Federal courts, and he is admitted to practice in California and Washington. Cameron is also qualified to appear before the Court of International Trade and the Federal Maritime Commission. 

    Discussions by the Court 

    The Court first set forth the legal standard for expert testimony under Federal Rule of Evidence 702, which requires expert opinion to be both relevant and reliable. The Court acted as a gatekeeper to evaluate admissibility of expert opinions. General qualifications of both experts were not disputed and the focus was on assessing the reliability and relevance of the expert testimony.  

    The Plaintiff sought to limit Cameron Roberts’ anticipated testimony related to the COVID pandemic, arguing that he lacked the qualifications and that his testimony would lack relevance and reliability. The Defendants intended for Roberts to provide insights into “the pandemic’s effects on the import industry” and how it specifically impacted individuals involved in the case and their ability to work. The Plaintiff’s main contention was that Roberts did not possess relevant education or specialized knowledge about the COVID pandemic, particularly in areas like medicine or public health. However, it’s important to note that Roberts did not claim to be a pandemic expert in those fields. Instead, his opinions were rooted in his expertise in the customs brokerage industry, shaped by his observations and personal experiences during the pandemic. 

    The Plaintiff did not appear to dispute Roberts’ general industry expertise, which formed the basis of his opinions. As such, Roberts was considered qualified to offer expert insights into the relevant industries during the pandemic based on his personal knowledge, experience, and observations during that time. 

    The Plaintiff attempted to challenge the reliability and relevance of Roberts’ opinions as they applied to the specific facts of the case. They pointed out that Roberts’ opinions were often based on facts that were either in dispute or about which he had limited personal knowledge. However, it was clarified that this argument primarily called in question the weight and credibility of Roberts’ opinion testimony, rather than its reliability or relevance. 

    The Defendants’ primary argument for excluding Thompson as an expert was based on the assertion that her disclosed affirmative report contained numerous improper legal conclusions. Thompson had made numerous legal conclusions within her testimony, specifically regarding whether the Defendants’ conduct constituted negligence, whether they breached a fiduciary duty, or otherwise violated federal regulations. She even made express credibility determinations.  Similarly, the Plaintiff contended that Roberts’ anticipated testimony was improper because it extensively included inadmissible legal opinions on contested issues. For instance, he had defined gross negligence, mistake of fact, and inadvertence based on case law that was irrelevant to the facts of the specific case. Ultimately, he had arrived at a legal conclusion, stating that the Radiant Defendants were not grossly negligent but had committed a mistake of fact. He found that the Radiant Defendants’ belief that they had submitted the appropriate paperwork was reasonable. The Court concurred that such testimony would not be admissible. 

    Consequently, the Court partially granted the Plaintiff’s motion to limit Roberts’ testimony and partially granted the Defendants’ motion to exclude Thompson’s testimony. The Court’s order stipulated that neither expert would be allowed to offer testimony during the trial that purported to provide impermissible legal conclusions or interpretations. 

     
    Court assessed the dispute regarding whether Thompson should be disqualified as an expert due to the form of her report. Defendants argued that her conclusions were based on a skewed version of the factual record consisting of “regurgitated facts” provided by the Plaintiff’s counsel. They contended that within her report, Thompson made improper determinations on the credibility and culpability of lay witnesses, and these issues, coupled with the alleged formulation of her opinions as legal conclusions, led them to seek her disqualification as an expert witness. 

    Concerning the formulation of her opinions in her report, it was noted that Thompson’s written report, as disclosed to the Defendants, wouldn’t be admitted into evidence since it would be redundant with the testimony she would provide at trial. The Court emphasized that objections to the form of her testimony could be raised during the trial, but disqualifying her as an expert wasn’t warranted. Instead, traditional means such as cross-examination, presenting opposing evidence, and instructing the jury on the burden of proof were deemed appropriate for challenging her testimony. 

    Plaintiff recognized that Thompson’s opinions regarding the credibility of lay witnesses were improper and had shown a willingness to address and correct this issue. However, there was one statement challenged by the Defendants that Thompson had not rectified, and the Court determined it to be improper. Specifically, the Court ruled that Thompson could not provide opinions on the state of mind or understanding of other potential witnesses. The Court prohibited Thompson from opining on the credibility or culpability of lay witnesses. 

    Regarding the potentially inadmissible formulations of Thompson’s opinions, it was argued that these issues were curable. Plaintiff provided revised language to address the alleged improper conclusions, demonstrating how they could be presented as admissible opinions without altering their substance. Defendants contested this amended report, claiming it was an untimely supplement. However, the Court noted that it could excuse the untimeliness if it found the disclosure error to be harmless. Furthermore, it highlighted that even without the modified report, Thompson could still provide admissible opinions within the scope of her original disclosure. 

    The Court’s role was to determine whether Thompson was qualified to offer relevant and reliable testimony. Since there were no challenges to the experts’ general qualifications, and given that both parties had dueling expert testimonies on the same subject matter, the Court believed the intended dueling testimony would be relevant and reliable as long as it was presented appropriately and in an admissible form at trial. 

    Held 

    The Court granted the motions only to the extent of excluding improper legal conclusions and credibility opinions. It denied excluding the experts themselves. The Court found Roberts qualified to opine on the pandemic’s industry impact from his experience. The Court held Thompson’s opinions could be presented in an admissible manner, finding her report did not warrant blanket exclusion. With improper opinions excluded, the Court found both experts could offer helpful industry testimony. 

    The Court has not arrived on an outcome for this case since the remaining issues involved in this case still await resolution. 

    Key Takeaways:

    – Experts can testify to industry practices and standards based on their qualifications and experience in the field. However, experts cannot offer legal conclusions or interpretations.  

    – Minor deficiencies in an expert report do not always warrant blanket exclusion of the expert. Their opinions can still be presented in admissible form through testimony.  

    – While experts cannot opine on lay witness credibility, they can otherwise testify to the reasonableness of parties’ actions based on industry standards and their expertise. 

    – Untimely supplementation of an expert report may be excused when it does not substantively alter the opinions and causes no prejudice. 

    In summary, the Court set a high bar for exclusion of otherwise qualified experts. Their opinions must be screened for legal conclusions, but as long as their testimony assists the factfinder and clearance requirements are met, exclusion is disfavored. 

  • California Court admits the testimony of film and television industry experts in copyright infringement action 

    California Court admits the testimony of film and television industry experts in copyright infringement action 

    This case involved claims of copyright infringement brought by WMTI Productions, WMTI Productions North, and The Next Season Company (Plaintiffs) against Kevin Healey, Propagate Content, and unnamed Does (Defendants). Plaintiffs alleged that certain episodes of Defendant’s shows Prank Encounters and Double Cross infringed on certain episodes of Plaintiff’s show Scare Tactics.

    Specifically, Plaintiffs alleged the following episodes infringed:

    • Prank Encounters “Camp Scarecrow” infringed Scare Tactics “Camp Kill”
    • Prank Encounters “Face Fears” infringed Scare Tactics “My Heart Belongs to Misery”
    • Prank Encounters “End of the Road” infringed Scare Tactics “Road Kill”
    • Prank Encounters “Split Party” infringed Scare Tactics “Send in the Clowns”
    • Prank Encounters “Graveyard Shift” infringed Scare Tactics “Bicentennialien”
    • Double Cross “Open House” infringed Scare Tactics “Room with a View”

    Defendants filed a motion for summary judgment arguing there was no genuine dispute of material fact on liability or damages. They also filed motions to exclude the testimony of Plaintiff’s proposed expert witnesses on liability (Paul Jackson) and damages (Tyler Massey).

    Film and Television Industry Experts

    Paul Jackson is a highly experienced film and television writer-producer, having worked in the industry since 1988. He has been a member of the Writers Guild of America since 1988, writing and producing numerous television series over his 30+ year career. His credits include serving as Executive Producer, Co-Executive Producer, Supervising Producer, and Consulting Producer on shows like Lois and Clark, Sliders, Charmed, She Spies, and When Calls the Heart. Since 1992, Jackson has arbitrated writing credits for the Writers Guild, which involves closely analyzing scripts and stories to determine the creative contributions of different writers. Through this work and his extensive experience as a “Writer-Staff” Producer, Jackson has developed expertise in comparing scripts and assessing similarities between stories, characters, sequencing, settings, and other elements. In this case, he was retained to analyze the alleged substantial similarities between Plaintiff’s Scare Tactics episodes and Defendant’s Prank Encounters and Double Cross episodes. Jackson provided detailed plot, character, sequence, setting, and mood comparisons between these works in his expert report, given his qualifications to conduct such analysis based on his 30+ years as a professional television writer and producer.

    Tyler Massey has over 20 years of experience in the film and television industry, including roles in international content distribution, acquisitions, licensing, and financial analysis. He has negotiated hundreds of deals for formats, finished productions, and media rights across broadcast, cable, SVOD, and AVOD platforms. Massey has extensive expertise in market valuation, revenue forecasting, and cost apportionment for television programming. He has worked for production companies, studios, and distribution firms, evaluating content sales strategies and revenue projections. In this case, Massey provided a damages analysis regarding lost revenues and brand value for Scott Hallock/WMTI based on alleged infringement and substitution of Defendant’s shows for a reboot of Scare Tactics. His industry experience qualifies him to opine on these matters.

    Discussions by the Court

    The Court denied Defendant’s motion for summary judgment on liability. The Court found there was a genuine dispute of material fact regarding substantial similarity under the extrinsic test, which looked at objective criteria like plot, themes, characters, etc. Plaintiff presented evidence about the selection and arrangement of unprotectable elements that could constitute an original work. The Court rejected Defendant’s argument that Plaintiff failed to properly invoke a selection and arrangement theory and found the allegations in the complaint gave adequate notice.

    The Court also denied summary judgment on damages. It found that Plaintiff presented evidence which supported at least some of their claimed damages categories tied to lost opportunities to monetize Scare Tactics due to the existence of Prank Encounters. For example, evidence indicated Netflix declined to exercise an option to produce new Scare Tactics episodes because its needs were satisfied after having acquired Prank Encounters around the same time.

    Defendant sought to exclude the expert opinions and testimony of Tyler Massey, Plaintiff’s proffered damages expert, on several grounds. First, Defendant asserted that Massey’s damages calculations had no relation to Plaintiff’s infringement allegations because he analyzed harm to the overall Scare Tactics format rather than damages resulting specifically from infringement of the six copyrighted segments at issue. However, the Court found that damages to the value of the broader Scare Tactics series were recoverable under 17 U.S. Code § 504, which allowed recovery for any harm caused by the infringement, not just harm to the intrinsic value of the copyrighted work. Second, Defendant argued that Massey’s testimony was unreliable because it relied on layers of speculation, including assuming Scare Tactics would have been rebooted if not for the existence of the show Prank Encounters. But the Court noted that assumptions are a necessary part of any damages calculation given the counterfactual nature of a world without infringement. As long as the assumptions were reasonable and grounded in evidence, any flaws went to the weight of Massey’s testimony rather than its admissibility. Third, Defendant sought to preclude Massey from opining on substantial similarity between the works accused of infringement and the asserted copyrighted works, an issue on which he lacked expertise. The Court agreed Massey could not offer his own opinion on similarity, but he could calculate damages based on the assumption that the works were substantially similar. Fourth, Defendant moved to exclude one category of Massey’s damages related to infringement of a wholly unrelated work, Joke’s On You, which seemed to stem from a settlement agreement rather than any copyright violation alleged in the case. Since this category did not arise from the claimed infringement, the Court excluded it. Aside from this one category, the Court otherwise denied exclusion of Massey’s damages calculations and held his assumptions and speculation permissible bases for expert testimony.

    Defendant separately sought to exclude the expert testimony of Paul Jackson, Plaintiff’s proposed witness on the similarities between the copyrighted Scare Tactics episodes and those of Defendant’s shows. Defendant argued Jackson failed to apply the extrinsic similarity test because he did not filter out non-expressive, unprotected elements before analyzing the works’ similarities. According to Defendant, this rendered Jackson’s opinion unreliable and unhelpful. However, the Court noted that wholesale filtering was not required under the selection-and-arrangement theory pursued by the Plaintiff, and in any event, Jackson’s similarity analysis methodology was valid and helpful to the factfinder. Which elements were protectable and which were unprotected scenes-a-faire was a factual issue for the jury to decide; Jackson could present his overall analysis, while Defendant could provide their own contradicting evidence on unprotected elements. Thus, Jackson’s failure to filter did not warrant exclusion but simply went to the weight the jury should accord his opinion. Defendant remained free to cross-examine Jackson and argue his testimony should receive little weight. But the Court denied exclusion of Jackson’s similarity analysis wholesale, finding his methodology sufficiently reliable despite the lack of filtering.

    Held

    The Court largely denied Defendant’s motion to exclude Plaintiff’s damages expert Tyler Massey, finding his assumptions and speculative damages calculations were permissible bases for expert testimony. The only exclusion was one category of damages unrelated to the asserted copyrights. Regarding Plaintiff’s liability expert Paul Jackson, the Court wholly denied Defendant’s motion to exclude his substantial similarity analysis. Despite Jackson’s failure to filter out unprotected elements, the court found his similarity analysis methodology was reliable and helpful to the factfinder. Any flaws in his approach went to the weight of Jackson’s testimony rather than its admissibility. Thus, aside from one minor carveout, the Court denied exclusion of the expert analyses of both Massey and Jackson. The Court has not arrived on an outcome for this case since the remaining issues involved in this case still await resolution.

    Key Takeaways

    • The motion to exclude the expert testimony of Paul Jackson in regards to substantial similarity was denied by the court as his methodology was reliable despite failing to differentiate the unprotected elements. The flaws in the methodology of Jackson raised issues for cross-examination and not for exclusion. 
    • The motion to exclude the expert testimony of Tyler Massey was partially denied. Massey was permitted to make assumptions in relation to the calculation of hypothetical damages. Massey was prohibited from providing opinions in relation to substantial similarity, as he lacked expertise. The damages unrelated to the asserted copyrights were excluded from the testimony of Massey. 
    • Disagreements or flaws regarding the expert testimony are often ruled to go to the weight of the testimony rather than admissibility. 

    In summary, the key takeaways are that  disagreements and questionable methodology choices generally should not be the grounds for the wholesale exclusion of the expert. In such scenarios, the court favors cross-examination and contrary evidence to address the flaws in the testimony of the expert.

  • Colorado Court weighs reliable basis of Pathology Expert’s testimony over semantics in medical negligence suit 

    Colorado Court weighs reliable basis of Pathology Expert’s testimony over semantics in medical negligence suit 

    Plaintiff, Deborah Duran pursued claims of medical negligence and malpractice against the Defendants, Donald Corenman, M.D.; Sean Bryant, M.D.; Jack Anavian, M.D.; The Steadman Clinic, Professional LLC; And Trystain Johnson, M.D. arising from the untimely death of her husband, Gilbert Duran due to a rare melanic schwannoma. Plaintiff is not only Mr. Duran’s widow but also acted as the personal representative of her late husband’s estate. The core contention in this case was that the Defendants, purported medical professionals, had delayed in diagnosing Mr. Duran’s schwannoma upon its initial discovery in 2015. This alleged delay led to the tumor metastasizing, ultimately resulting in Mr. Duran’s demise in 2019. Plaintiff sought to preclude certain opinions of defense expert Dr. Gross regarding the tumor’s likely characteristics and poor prognosis in 2015, but the Court admitted it regardless because it weighed reliable basis over semantics dispute. 

    Anatomic Pathology Expert 

    John McMahon Gross, M.D., M.S. had been designated by the Defendants to provide expert testimony regarding the pathology issues in this case and offer an opinion on the likely characteristics of the tumor back in 2015. Following pathology residency, Dr. Gross pursued specialized fellowship training in bone and soft tissue at the University of Washington in Seattle, WA followed by additional fellowship training in surgical pathology at the Mayo Clinic in Rochester, MN. In 2020, Dr. Gross became an assistant professor in the Department of Pathology at Johns Hopkins where he specializes in bone and soft tissue and surgical pathology. Dr. Gross has an academic interest in bone and soft tissue tumors and has authored over a half dozen articles and chapters and given national and international presentations on sarcoma pathology. Dr. Gross’s stance was that the tumor had been malignant in 2015, carrying a grim prognosis even with early intervention. 

    The Plaintiff sought to exclude a specific facet of Dr. Gross’ expert opinion from consideration. 

    Discussions by the Court 

    Citing his March 30, 2022 expert report, the Plaintiff presented several arguments to strike Dr. Gross’ opinion that increased mitotic activity predicted malignancy. First, the Plaintiff contended that Dr. Gross had failed to provide supporting medical literature for this opinion which rendered it unsupported and undermined its credibility. Second, the Plaintiff argued that this opinion was irrelevant to the central issues of the case since it lacked empirical backing to contribute meaningfully to the understanding of Gilbert Duran’s circumstances. Third, even if considered relevant, the Plaintiff invoked Rule 403 of the Federal Rules of Evidence which suggested that any potential probative value of the unsupported opinion was outweighed by its potential for confusion or prejudice. 

    In response, the Defendants asserted that the Plaintiff’s contentions were mischaracterizations of Dr. Gross’ opinion and its underpinnings. They argued that the Plaintiff had introduced the term “predict” during the deposition, whereas Dr. Gross had framed his opinion as an association or correlation between mitotic activity and poor prognosis. The Defendants further maintained that Dr. Gross’ opinion was built upon sufficient facts and data and highlighted the Plaintiff’s own reference to the Torres-Mora study that supported his stance and was thoroughly discussed during Dr. Gross’ deposition. The Defendants contended that Dr. Gross’ opinion was reliable, relevant, and logically derived from existing scientific knowledge. 

    In conclusion, the Court faced the critical task of evaluating the admissibility of Dr. Gross’ opinion, specifically his opinion which suggested an association or correlation between high mitotic rates and poor prognosis. The outcome of this decision held significant weight, as Dr. Gross’ expert testimony had the potential to shape the Court’s understanding of the medical aspects of the claim. Balancing the arguments presented by both parties, the Court’s determination would impact the course of the case and potentially influence the attribution of liability and the assessment of damages. 

    Plaintiff’s central argument revolved around their assertion that Dr. Gross intended to provide testimony which suggested that increased mitotic activity in 2017/2018 predicted aggressive behavior of tumors and was predictive of the tumor in 2015. The Plaintiff equated this opinion with the notion that mitotic rate predicted malignancy. Additionally, the Plaintiff emphasized the viewpoint of Dr. Folpe, Dr. Gross’ mentor and a respected expert in the field, who disagreed with Dr. Gross’ opinion and did not subscribe to the belief that mitotic rate predicted metastasis. The Plaintiff fervently urged the Court to strike Dr. Gross’ opinion about increased mitotic activity being predictive of aggressive behavior. 

    The Plaintiff conflated the term “predicts” with “causation” in their argument which further intensified the matter. They illustrated this by drawing an analogy which asserted that just as a correlation between ice cream sales and shark attacks did not imply that consuming ice cream caused shark attacks, a similar principle applied to the correlation between increased mitotic activity and metastasis. The Plaintiff contended that association was never the same as prediction and exemplified this with the analogy of a person associating with a criminal not necessarily predicting that the individual will commit a crime themselves. 

    However, the Court concurred with the Defendants’ stance that the Plaintiff aimed to exclude an opinion that Dr. Gross did not actually present. After carefully examination of Dr. Gross’ written opinion and deposition testimony, it was apparent that the core of his written opinion centered on Mr. Duran’s tumor being an exceptionally rare type of sarcoma which possessed aggressive traits and a malignant histology. Dr. Gross maintained that the aggressive features noted in the tumor’s 2018 diagnosis were likely present in 2015 which indicated a bleak prognosis even if diagnosed earlier. He argued that the aggressive nature of the tumor would have made a significant impact even if treated in 2015. Dr. Gross concluded by stating that the tumor’s aggressive attributes and the presence of these traits in 2018 imply their existence in 2015, and that early diagnosis and treatment may not have prevented recurrence or metastasis. 

    Contrary to the Plaintiff’s assertions, nowhere in Dr. Gross’ report did he offer the specific opinion that a high mitotic rate predicted malignancy. Even during his deposition testimony, when asked about whether he believed that mitotic activity was predictive of malignant behavior, Dr. Gross responded by saying that it had been associated with a worse prognosis. Despite further pressing from the Plaintiff’s counsel, Dr. Gross consistently maintained that mitotic activity had been merely suggestive or associated with an unfavorable outcome. 

    In conclusion, the Plaintiff’s argument hinged on the interpretation that Dr. Gross asserted a predictive link between increased mitotic activity and aggressive behavior of tumors. However, the Defendants and the Court contended that Dr. Gross’ opinion did not explicitly express such a predictive relationship, but was suggestive of a relationship of association between a poor prognosis and high mitotic activity present in the subject tumor. This nuanced distinction became pivotal in determining the admissibility and weight of Dr. Gross’ expert testimony within the context of the case. 

    The crux of the dispute in this case appeared to center around a semantic distinction. The Plaintiff seemingly equated the phrase “predictive of” with terms like “caused” or “causation.” However, the Court did not find that Dr. Gross’ opinion, as articulated in both his written report and deposition testimony, could be interpreted as encompassing a notion of prediction. Furthermore, even if it were assumed to involve prediction, in the realm of medicine, “predictive” did not necessarily denote causation. The term “predictive value” in a medical context, as defined by Stedman’s Medical Dictionary, referred to the likelihood that a given test result correlates with the presence or absence of a disease. This definition aligned with Dr. Gross’ medical opinion and underscored the Court’s understanding that his opinion was grounded in a correlation, not a statement of causality. In other words, the court weighed the reliable basis over semantics. 

    The Plaintiff’s challenge to Dr. Gross’ qualifications or experience did not seem to hold weight in this argument. Dr. Gross evidently derived his opinions not solely from referenced medical literature and scientific sources, but also from his substantial education, training, and experience as a pathologist. Moreover, the Court deemed the Torres-Mora study and the World Health Organization Classification of Tumors – Soft Tissue and Bone Edition (5th Ed.), in conjunction with other factors referenced in Dr. Gross’ report, as sufficient support for his opinion. This collective foundation rendered his opinion adequately reliable. 

    Held 

    Dr. Gross’ opinion regarding any observed association, suggestion, or correlation between heightened mitotic activity and a poor prognosis in the specific tumor in question was indeed relevant to the Plaintiff’s claim of delayed diagnosis and the Defendants’ defenses. Considering all factors, the Court found no substantial basis under Fed. R. Evid. 403 to exclude Dr. Gross’ opinion from the proceedings. This ruling acknowledged the relevance, reliability, and context of Dr. Gross’ testimony within the broader framework of the case. 

    The Defendants have effectively fulfilled their obligation to demonstrate that Dr. Gross’ opinion met the criteria stipulated in Fed. R. Civ. P. 702. It is worth noting that the Plaintiff retained the prerogative to subject Dr. Gross to thorough and respectful cross-examination regarding the matters addressed in her motion and during Dr. Gross’ deposition. Consequently, the Court denied the motion and upheld the admissibility of Dr. Gross’ opinion as evidence in the case. Since the remaining issues are yet to be resolved, the Court has not reached a final outcome for this case as of now.

    Key Takeaways 

    1. The Court rejected the Plaintiff’s argument that the expert’s opinion lacks sufficient basis and should be excluded as irrelevant or prejudicial. 
    1. The Court found the defense expert does not actually opine that mitotic activity predicts tumor metastasis or malignancy, only that there is an association or correlation between high mitotic rates and poor prognosis. 
    1. The Court viewed the dispute over the language used by the expert as merely semantic in nature. The term “predictive” does not necessarily imply causation in a medical context. 
    1. The Court held the expert’s opinions are sufficiently reliable based on his qualifications/experience as a pathologist and the medical literature cited in his report. 
    1. The Court found the expert’s views relevant to the issues in the medical malpractice case regarding delayed diagnosis and defenses. 
    1. The Court ruled the defense satisfied its burden under Rule 702 to show the testimony is admissible expert opinion. 
    1. The Court emphasized the Plaintiff can vigorously cross-examine the expert about his opinions at trial. 
    1. The Court denied the motion to strike/preclude the expert’s testimony, allowing him to offer opinions at trial on the characteristics of the tumor and likely prognosis. 

    In summary, the key takeaways are that the Court allowed the defense expert to testify despite Plaintiff’s challenges, finding his opinions supported, relevant, and reliable based on the appropriate expert methodology and standards. The Court saw flaws only in the semantics used to describe the opinion, not the underlying basis.
