About Us

Founded in 1976, Birch, Stewart, Kolasch & Birch, LLP ("BSKB") is an internationally-recognized and highly-respected international intellectual property law firm committed to obtaining and enforcing IP rights for our clients.

BSKB has been providing a full range of intellectual property law services to clients for over 30 years. We specialize in the practice areas of chemical patents, mechanical patents, cleantech and biotechnology patents, life sciences patents, electronics and IT patents, trademark and copyright law, litigation dispute resolution, and post-grant patent review--including the reexamination and reissue of patents.

We believe in offering every client quality, personalized service. We also believe that further education is one of the best ways to help clients make the most of their intellectual property. This is why every year we offer seminars on U.S. patent and trademark law, including patent interference, opposition, patent prosecution and litigation. These seminars include participants from the U.S. and around the world.

BSKB offices are located in Falls Church, Virginia and San Diego, California, though we faithfully serve clients across the United States and internationally.

BSKB has consistently ranked among the top three patent firms in the United States and is also ranked in the top 15 trademarks firms.

We're ready to protect your intellectual property rights. Contact BSKB today to discuss how we can help you protect the intellectual property in which you have invested time and resources.
