Firm Report: The Line Between Bio and Technology

The question of what the biotechnology industry can patent ripened into a broad industry debate after two landmark Supreme Court decisions – Mayo Collaborative Servs v. Prometheus Labs., Inc. (2012) and Alice Corp. v. CLS Bank International (2014).  Their collective holding – that under 35 U.S.C. § 101, inherently natural phenomena cannot be patented, even with the addition of previously known secondary technologies – led to the invalidation of numerous patents and likely narrowed the scope of what can be patented in the future.

Benjamin K. Riley Publishes Article in the Litigation Magazine on Trying a Trade Secret Case: A Road Map

Trade secret trials challenge and engage all of a trial lawyer’s essential skills and training. Dealing with state-of-the-art technology–intricate circuit designs, sophisticated manufacturing processes, or highly complex formulas–is often a huge challenge, but there are other pitfalls for the unaware lawyer. Special care must be given in these cases to issues of disclosure, discovery, the preparation of witnesses, the handling of experts and juries, and the use of graphics and technology in the courtroom. With legal and other barriers being erected in patent litigation and with the recent passage of the federal Defend Trade Secrets Act of 2016, trade secret cases have moved to the forefront of technology litigation. Trade secrets litigators must understand the unique and critical strategies, requirements, and hazards presented by the trial of a technical trade secret case. View a PDF of the article.
