    • Obtained a Non-Suit in a wrongful death case in Delaware County. The Court found upon Motion that there was no link to causation after extensive, nuanced argument. (2025)
    • After an 11-day trial, obtained a defense verdict on behalf of four physicians and a major teaching hospital in Philadelphia. The medical malpractice action involved the labor and delivery of a baby later alleged to have a hypoxic birth injury that caused developmental delays and permanent brain damage, among other issues.

    • Secured a unanimous defense verdict in Philadelphia on behalf of a prominent orthopedic surgeon accused of inappropriate touching of a patient. The plaintiff alleged that the physician inappropriately touched her during a preoperative examination for bilateral hip surgery. Through meticulous cross-examination and persuasive argument, the defense team achieved a complete victory. (2025)
    • Obtained a dismissal in the middle of trial after cross-examining the plaintiff’s witnesses in a case involving a former NFL player and opera singer who contended they had permanent injuries after knee surgery and the failure to diagnose a pseudoaneurysm.

The jury was receptive to the defense arguments that, in fact, the doctor not only complied with the standard of care, but exceeded it. (2024)
    • Achieved a unanimous defense verdict in a wrongful death case. The lawsuit included allegations of failure to workup and diagnose lung cancer. The 9-day trial revolved around the care provided by the primary care and orthopedic physicians. The plaintiffs claimed the patient’s symptoms were related to a Pancoast tumor that was undiagnosed, resulting in his death. Gary was able to establish with the jury the superiority of the defense experts by comparison, and explain there can be concurrent diseases and there was an objective reason for each and every one of the patient’s symptoms. (2024)
    • Secured a unanimous defense verdict on behalf of a cardiologist cardiologist who was accused of causing the death of a patient. The plaintiff contended the cardiologist should have immediately sent his patient to the hospital for an emergent cardiac catheterization due to unstable angina. Gary persuaded and convinced the jury that the patient indeed had stable angina and did not need urgent care, even though the patient died four days after the visit. (2024)
    • Secured a defense verdict on behalf of a gynecological surgeon facing accusations of damaging a woman’s ureters and urinary tract during a laparoscopic hysterectomy.

The key issue in the case revolved around presentation in the emergency room and the interpretation of an ultrasound as well as the presenting symptoms and complaints of the plaintiff. (2024)
    • Secured a unanimous defense verdict after a six-day trial on behalf of a primary care physician accused of failing to timely diagnose cancer. The unanimous verdict was reached after a thorough and aggressive cross-examination of experts. Gary persuaded the jury that the doctor’s actions were appropriate and that no CT screening was required for this patient despite their extensive smoking history. (2024)
    • After an 8-day trial regarding the death of a patient, Gary obtained a unanimous defense verdict on behalf of an interventional cardiologist. The plaintiff alleged the doctor was negligent in his interpretation of an echocardiogram and in the performance of a ventriculogram during a cardiac catheterization. Gary succeeded in presenting expert testimony from four different specialties to persuade the jury his client acted appropriately at all times. Aggressive cross-examination of plaintiffs' experts contributed greatly to the victory. (2023)
    • Secured a defense verdict after a nine-day trial where the jury found no liability for a primary care physician who was accused of making improper referrals to a weight loss physician and failing to work up a 36-year-old obese woman for cardiac issues. The decedent left behind a 4-year-old son and quadriplegic husband making the case extremely sympathetic. (2023)
    • Secured a unanimous defense verdict in Chester County on behalf of a podiatric surgeon after a six-day trial. Plaintiffs alleged the doctor failed to meet the standard of care by not closely observing a patient in follow-up post-surgery on a severe Charcot foot, allowing an infection that led to a below-the-knee amputation. The trial involved seven experts and complicated medicine regarding various infectious pathogens. (2023)
    • Secured a defense verdict for two anesthesiologists accused of malpractice. The plaintiffs had claimed the anesthesiologists failed to properly hydrate the patient during the procedure as well as adequately and appropriately monitor the blood pressure and heart rate. They were also criticized for extubating prior to the patient meeting the necessary criteria. The plaintiffs alleged the deficiencies resulted in poor perfusion to the bowel which led to necrosis and resection leaving the patient with short gut syndrome and cognitive deficits. The jury commented on the effective cross-examination and the quality of the defendants’ experts as being important in their analysis. Raymond Petruccelli was instrumental in the defense of this case. (2023)
    • Obtained a defense verdict for a lab director, hospital and health care system. Gary was asked to “parachute” in two weeks before trial and represent these health care providers. The complex case involved a lab mix-up that caused plaintiffs to have unnecessary surgery in the form of a radical prostatectomy for prostate cancer. The surgery caused complications of stress urinary incontinence and erectile dysfunction. The plaintiff made an eight-figure demand and the trial lasted eight days. (2023)

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

The Enforceability of Online Arbitration Agreements Remains Unresolved in Pennsylvania, But the Pennsylvania Superior Court has Provided Substantive Guidance on the Issue

Key Points: The Pennsylvania Supreme Court confirms that an order compelling arbitration is not immediately appealable as collateral orders. The outcome of Chilutti II has generally left the substantive enforceability issues with browsewrap agreements unresolved in Pennsylvania. Until this issue is resolved by the Pennsylvania courts, companies operating in the Commonwealth should strive to ensure that their registration websites and/or application screens conspicuously present arbitration agreements in manners which ensure their users and consumers assent to the terms of the agreements by following the standards set forth in Chilutti I. Browsewrap agreements have been defined as agreements “‘in which a website offers terms that are disclosed only through a hyperlink and the user supposedly manifests assent to those terms simply by continuing to use the website,’ and typically do not require an electronic signature.” See, Cobb v. Tesla, Inc., 2026 WL 458470, at *1 n. 2 (Pa. Super. Feb. 18, 2026) (citation omitted). They are largely regarded as the “if you keep using this, you agree to everything buried in this link” terms embedded into almost every online agreement consumers and users sign before proceeding with purchases of goods and/or services. While consumers are generally aware of them, many almost never click on the link, nor read them in their entirety. This leaves many consumers and users ignorant of the terms and impact of such agreements. However, one’s ignorance of the otherwise neatly-tucked-away terms rarely renders them unenforceable. The issue of the enforceability of browsewrap agreements has been up for debate for some time in many jurisdictions, including Pennsylvania. Indeed, Pennsylvania had a brief grip on this issue for a period in time. Specifically, in 2023, an en banc Superior Court set forth heightened standards for companies to meet in order to secure assent and enforce browsewrap arbitration agreements. See Chilutti v. Uber Techs., Inc., 300 A.3d 430 (Pa.Super. 2023) (en banc) (“Chilutti I”) Chilutti I involved a husband and wife who sued Uber and its subsidiaries after the wife, a wheelchair bound passenger using Uber’s rideshare service, fell, struck her head, and lost consciousness due to her uber driver failing to provide a seatbelt and making an aggressive turn during the trip. The Chilutti’s filed a negligence lawsuit against Uber and its subsidiaries. In response, the defendants moved to compel arbitration, arguing that “the couple’s conduct on the company’s website and application — when they registered for the ridesharing service — signified that they agreed to be bound by the mandatory arbitration provision found in the hyperlinked terms and conditions.” The trial court granted the defendants’ petition and stayed the proceedings pending the results of arbitration, and the Chilutti’s appealed. On appeal, the Superior Court addressed two issues. First, it addressed the issue of whether it had jurisdiction to hear the appeal. A divided Superior Court determined that it did, with its basis for the holding being that the order from which the Chilutti’s appealed was a collateral order. Next, the Superior Court set out to address the merits of the Chilutti’s substantive claim. The Superior Court concluded that the parties lacked a valid agreement to arbitrate. Its rationale was that Uber’s website and application did not provide reasonably conspicuous notice of the terms to the Chiluttis. In reaching this decision, the en banc Superior Court held that browsewrap arbitration agreements are enforceable in Pennsylvania only if the registration website and application screens explicitly inform consumers that they are waiving the right to a jury trial, the registration process cannot be completed until the consumer is fully informed of this waiver, and, when the agreement is available via hyperlink, the waiver appears at the top of the first page of the terms in bold, capitalized text. Since the ruling, Pennsylvania courts have applied Chilutti I to determine if browsewrap agreements are enforceable.  For instance, the Allegheny County Court of Common Pleas invoked Chilutti I to reject an agreement that lacked an express jury-trial waiver on the assent screen.  See Miller v. Festival Fun Parks, LLC, 92 WDA 2025 (C.P. Alleg. Cnty. Mar. 24, 2025). Similarly, the Superior Court has held that notice which failed to explicitly state the consumer was waiving a jury-trial right did not “me[e]t the strict burden set forth by our en banc Court in Chilutti I.” Pierce v. FloatMe Corp., 348 A.3d 1077, 1088 (Pa. Super. 2025). While the issue of enforceability of browsewrap agreements appeared to have been resolved by Chilutti I, Pennsylvania courts’ grip on this issue has been slackened by the Pennsylvania Supreme Court’s January 21, 2026, opinion in Chilutti II. See Chilutti v. Uber Techs., Inc., 349 A.3d 826 (Pa. 2026) (“Chilutti II”). Therein, the Supreme Court did not address the merits of the Chiluttis’ substantive claim, but rather the issue of whether the Superior Court had appellate jurisdiction to immediately review the orders staying litigation pending arbitration. The Court ultimately vacated the en banc opinion on jurisdictional grounds, holding that the Superior Court did not have appellate jurisdiction because the trial court’s order from which the Chiluttis appealed did not qualify as a collateral order and, thus, the Superior Court erred in holding to the contrary and lacked jurisdiction to entertain the merits” of the Chiluttis’ substantive claim. As such, Chilutti II has rendered Chilutti I nonbinding, and the issue of enforceability of online arbitration agreements remains unresolved. However, in light of the fact the Supreme Court did not address or comment on the merits of the Chiluttis’ appeal, Chilutti I is still meaningful. Specifically, it provides guidance as to the standards a company should strive to meet to ensure they have obtained users’ assent so that they are able to enforce online arbitration agreements. Additionally, it may serve as persuasive authority in judges’ evaluations of petitions and/or motions to compel browsewrap arbitration agreements until this particular issue is properly put before our appellate courts.
