There was a slight uptick in district court filings last week after a slow January and February, with 43 new patent filings, including a design patent battle involving tumblers and multiple filings indicating an association with high-volume plaintiffs such as Jeffrey Gross and Leigh Rothschild.It was a busy week at the Patent Trial and Appeal Board (PTAB), with over 32 new challenges last week, with only one procedural denial on an institution decision-but that was not based on discretionary denial, which remains often briefed but rarely successful for the time being.
