David M. Welch

David M. Welch is a patent litigation attorney primarily representing plaintiffs in intellectual property disputes, with his practice centered at Welch, Crump, Albano & Slater. His tracked appearances indicate a focus on complex technology areas, specifically involving software and streaming media.

Welch has acted as lead counsel in the case of Dish Technologies L.L.C. v. Vidgo, Inc., where his client, Dish Technologies, asserted patents related to multi-bitrate content streaming or adaptive bitrate technology. These patents cover mechanisms that allow video stream quality to adjust in real-time based on connection speeds. This case is part of a broader enforcement effort by Dish against various streaming services over adaptive bitrate technology patents.

While David M. Welch's direct involvement in Inter Partes Review (IPR) or Post-Grant Review (PGR) proceedings is not evident from available records, the patents central to his Dish Technologies litigation have been subject to Patent Trial and Appeal Board (PTAB) review. For instance, elements of one of Dish's key adaptive bitrate patents ('554 patent) were voided by the USPTO's PTAB, a decision subsequently appealed by Dish to the Court of Appeals for the Federal Circuit. Based on tracked appearances, Welch exclusively represents plaintiffs in patent infringement actions.
