Dave Croston is a patent attorney and head of the Advanced Engineering group at Withers & Rogers. He is also the co-chair of the firm’s Contentious Practice group.

Dave has an active contentious practice, with a track record of cases before the Court of Appeal, the High Court and the Patent County Court (now the Intellectual Property Enterprise Court) as well as in oppositions and appeals at the European Patent Office.

Dave acts for clients in a diverse range of technology sectors such as aircraft propulsion, motorsport, homewares, packaging, medical devices and agricultural engineering to name a few.

Dave ran the successful appeal at the Court of Appeal in Vector Corporation vs. Glatt Air Techniques, Inc., the first successful Court of Appeal case by a Patent Attorney Litigator on appeal from the High Court.

Another of Dave’s notable achievements was securing a rare and substantial cost award at the European Patent Office on behalf of his client, one of the biggest ever granted by that tribunal.
