The Daily Journal recently named Mintz Member Siegmund "Sige" Gutman, Life Sciences Litigation Chair and Patent Litigation Co-chair, to its list of 2025 “Top Intellectual Property Lawyers.”

Sige is a highly sought-after IP trial lawyer and litigator with extensive legal, industry, and scientific experience in biopharmaceuticals, molecular and cell biology and biophysical chemistry. Regarded as one of the top life sciences patent litigators in the country, Sige’s clients entrust him to protect the intellectual assets most crucial to their businesses and to create market opportunities for their most important products. His team includes more than a dozen life sciences litigators representing clients in U.S. District Courts, the Federal Circuit, the PTAB, international jurisdictions, and arbitrations. 

The publication highlighted Sige’s complex problem-solving skills and notable cases representing Sanofi and SK Chemical in invalidating all 45 claims of a pivotal Pfizer patent covering pneumococcal conjugate vaccines. Daily Journal also noted his representation of Amgen in cases under the Biologics Price Competition and Innovation Act to defend their Prolia® and XGEVA® franchises from biosimilar competition. 

In addition to this Daily Journal recognition, Sige's success has also been acknowledged by Chambers (Life Sciences: IP/Patent Litigation California), LMG Life Sciences (General Patent Litigator of the Year – California), Best Lawyers (Lawyer of the Year, Los Angeles, Biotechnology and Life Sciences), Daily Journal (Top Intellectual Property Lawyer), IAM Patent 1000, Managing Intellectual Property IP Stars, Benchmark Litigation, and Legal 500.
