From its start, the Blog has railed against certain expansions of traditional product liability that could have negative impacts on scientific progress and the availability of good medical products. Innovator liability, first described in Conte back in 2008, is a good example of a bad idea. Its offspring, the so-called duty to innovate

A Detour Through Materials Science, Followed By A Climb Up A Rule 702 Hill

This post is from the non-Butler Snow side of the blog.
When you represent medical device manufacturers in product liability litigation, you will deal with allegations that a device broke or failed because of what it was made from, and you will encounter both experts and “experts” (scare quotes intended) in materials science.

New Law Review Article Explains the History and Application of Amended Fed. R. Evid. 702

There have been some famous law review articles, such as R. Coase, “The Problem of Social Cost,” J. of Law and Economics (1960), and S. Warren & L. Brandeis, “The Right to Privacy,” Harvard L. Rev. (1890). Those articles made waves when they came out, and they were cited endlessly. But when was the last…
Federal Judge In California Burns Both Sides With Expert Rulings

The District Judge in Lin v. Solta Medical, Inc. is evidently on a year-end push. We reported just the other day on the court’s order granting summary on the plaintiff’s warnings-based claims, but denying summary judgment on design defect. A few days later, the court ruled on the parties’ motions to exclude expert opinions. This…
Generic Causation Experts Excluded In Sweeping Ruling From The Acetaminophen MDL

It is not uncommon that terms are used without knowledge of their origin and that the origin is instructive about the meaning or proper application of the term. We offer two examples. Many lawyers who at least dabble in product liability litigation have heard the term “Bradford Hill criteria.” Was it named after two different…
Plaintiff’s Expert’s “Gut” Feeling Not Enough to Withstand Rule 702 or Summary Judgment

Listen to your gut. Follow your instincts. Trust your intuition. Great advice in many situations. Like deciding whether to buy skinny jeans or whether to buy your forever home. Or, when things seem “off” or feel “dangerous.” Or, when your body is trying to tell you something about your health. These are all times to…
Bogus Science Leads To Federal Preemption In The Ninth Circuit

A recent published opinion from the Ninth Circuit covers two issues near and dear to our hearts—federal preemption and claims based on outside laboratory testing. We care about federal preemption because . . . well, because we are the Drug and Device Law Blog, where there are some weeks when we write on preemption every…
More Exclusions of Pelvic Mesh Plaintiff Expert Opinions

We are headed to Guitar Town. That’s Nashville to you. Guitars are played and guitars (including the magnificent Gibson ES-335) are made there. We aim to sample plenty of live music and hot chicken. But the reason for our trip is the Defense Research Institute (DRI) Drug and Medical Device Conference. Tomorrow we will be…
D.Mass. Limits Plaintiff Experts in False Claims Act Case

We are on a DRI panel this September in Nashville discussing challenges to expert testimony, so we are especially vigilant when it comes to new cases on this subject. The rulings on expert admissibility in United States v. Biogen Idec., Inc., 2022 U.S. Dist. LEXIS 120549 (D. Mass. July 8, 2022), are not especially…
Casting Doubt And Poking Holes—Defense Causation Opinion Admissible Even If Not To A Reasonable Probability

A very helpful to-be-published opinion from the California Court of Appeal caught our eye this week because it comes out the correct way on an issue that has always bothered us: Does a defendant (not the plaintiff) in a product defect case have to offer evidence on medical causation to a reasonable degree of medical…
