Over 10 years ago, Wagenknecht IP® began as a patent prosecution law firm focusing almost exclusively on patenting San Diego’s biotechnology and life science inventions for start-ups.  Although our practice has expanded to include other technologies and international companies, Wagenknecht’s biotechnology practice is still a large part of the firm and is still known throughout San Diego under the moniker BIOTECH BEACH LAW .

Biotechnology inventions are highly scrutinized during examination.  US examination policies are shifting with respect to DNA, protein and diagnostic-based inventions, where further distinctions compared to natural biological processes must be considered.  In addition, complying with the written description requirement to obtain broad patents to encompass sequence variations often requires providing mutation analysis to identify critical sequences for binding or activity.

Wagenknecht continues to adapt its patent drafting strategies to stay ahead of trends in biotechnology examination policies.  Wagenknecht helps protect:

  • Protein, antibody & polypeptide sequences
  • Nucleic acid technologies
  • Transgenic organisms
  • Enzymatic processing methods
  • Drug delivery systems
