We round up the most significant appellate decisions relevant to commercial litigation each week.

Welcome to The Contingency‘s Commercial Roundup for June 28!

Since our last issue, much has happened, not least FeedSpot’s recognition of The Contingency as one of the 30 Best Antitrust Law Blogs and Websites.

The courts have also stayed busy as spring turned to summer. The U.S. Supreme Court ruled in two cases of interest to commercial trial lawyers and their clients. One of them breathes new life into a “consent” basis for personal jurisdiction (see Due process allows), and other resolves whether the federal Arbitration Act requires district courts that grant motions to compel arbitration to stay their proceedings (yes) (see Court must stay).

The Federal Circuit issued opinions in patent cases on obviousness (Use of two compounds) and co-inventors (Expandable hose patent). The Court also tossed the Trademark Trial and Appeal Board’s decision in a dispute over registration of a trademark that a trademark holder claimed would confuse consumers (TTAB mis-weighed), while the First Circuit upheld denial of attorney’s fees under the Copyright Act (Fight over who authored).

Meanwhile, the Third Circuit addressed a question of “falsity” under the Securities Exchange Act of 1934 (Claim that life insurer knew) and a question of “wrong-forum tolling” of limitations as an alternative to tolling that applies in the class-action context (American Pipe tolling).

The Eleventh Circuit’s decision in an appeal about discovery sanctions provides guidance on using “memory aids” and instructing witnesses not to answer question in depositions (WItness’s overuse).

The New York Court of Appeals upheld a “negligent supervision” claim against an investment bank (Investor stated), and the Supreme Court of Texas handed down several opinions on an array of subjects–limitations (Limitations defense may work), spoliation (Loss of video), sovereign immunity for claims arising from Winter Storm Uri (ERCOT dodges), non-liability of a plant owner’s owners under a “negligent undertaking” theory (Explosion of plant), and redemption of a law firm shareholder’s shares (Law firm founders).

Have a terrific Fourth of July weekend and holiday.
