Osha Liang Once Again Named to Top 10 List for TC 3600 Allowance Rates

Osha Liang has once again achieved a top-10 ranking by Juristat in patent examination allowance by the U.S. Patent and Trademark Office’s (USPTO) Technology Center (TC) 3600.

The USPTO’s TC 3600 provides examination for a wide range of technologies, including software, business methods, and the oil and gas industry. With an allowance rate of 80.7 percent, Osha Liang was recognized as one of the most successful firms in this challenging technology unit.

The TC 3600-selected law firms are all based in the United States and have disposed of at least 500 applications in TC 3600 during the 10-year period from 2006-2015.  The overall allowance rate for TC 3600 is 66.1 percent, which is below the USPTO average of 72.0 percent.

TC 3600 has become increasingly complex to navigate after the Supreme Court’s decision in Alice v. CLS Bank, which narrowed the patentability of certain types of inventions, including those in the software field.
