The longest time between a patent being filed and granted in December in Torrance was 3,042 days, according to the United States Patent and Trademark Office.

The patent application was filed by Tara Chand Singhal for apparatus and method for an integrated reuseable injection device with a medicine vial for home users. It was filed on Aug. 30, 2013 before being approved on Dec. 28, 2021.

Though patents are required for inventions and products, the granting of a patent is not a guarantee for success. Dennis Crouch, co-director of the Center for Intellectual Property & Entrepreneurship, said roughly 50 percent of patents expire prematurely due to costs.

There were 35 patents granted for Torrance inventors in December.
