The two technology centers that “grew” the most were 2400, Computer Networks, Multiplex, Cable and Cryptography/Security, and 3700, Mechanical Engineering, Manufacturing and Products, both of which experienced a 28% gain. They were closely followed by 2600, Communications, which grew 25%.
There were five Technology Centers which received a smaller share of granted patents in 2021 compared to 2011. 1700, Chemical and Materials Engineering, experienced a 18% decline, and 1600, Biotechnology and Organic received a 17% decline. 2800, Semiconductors, Electrical and Optical Systems and Components had a smaller decline of 10%. The smallest declines were 3600, Transportation, Electronic Commerce, Construction, Agriculture, Licensing and Review, with a 6% decline, and 2100, Computer Architecture Software and Information Security, which saw a 4% decline.
What caused each of these changes? Technology shifts over time as new industries appear and others are made obsolete. In our next sets of newsletters, we’ll dig into each of these Technology Centers and examine the changes over time in further detail.
