YOUR GO-TO INTELLIGENCE RESOURCE FOR THE SCHOLARLY PUBLISHING INDUSTRY

CAS, a division of the American Chemical Society, recently completed a major project with The National Institute of Industrial Property (INPI) of Brazil to implement an enhanced examination workflow solution for chemistry patent applications using a unique blend of technology, artificial intelligence, data, and expertise. The new solution reduced application examination times by up to 50%, helping the office achieve its goal of clearing 80% of its multi-year application backlog.

Brazil’s rapid growth caused patent application volume to outpace the patent office’s examination capacity. The new, optimized examination workflow uses CAS’s AI technology and eliminates a significant number of examiner search steps, allowing the office to better keep pace with projected application volumes.

CAS worked with INPI Brazil to tailor a solution to their unique needs. By employing multiple AI algorithms trained with patent office data and the scientist-curated CAS Content Collection™, the approach meaningfully increased examiner productivity. INPI Brazil reported that the CAS solution significantly reduced examiner search times for 77% of national applications processed, and that 29% of national applications processed required little or no additional search.

In 2021, CAS received the Stu Kaback Business Impact Award from the Patent Information Users Group (PIUG) recognizing the solution’s impact on INPI Brazil’s success. The underlying prior art search technology is implemented in CAS’s flagship solutions, STNext® and CAS SciFindern, to support more efficient and comprehensive prior art searching across the innovation journey.
