Non standard definition referring to the shot patent?

AstraZeneca, Johnson & Johnson and Gilead lead a crowded field of drug makers who excessively extend patent protections to limit the market entry of competing products in an anti-competitive practice called “evergreening,” a primary driver of high drug prices. This is one finding of many according to a public database created by the Center for Innovation (C4i) at UC Hastings Law.

The searchable database is the first of its kind to comprehensively track the patent protections filed by pharmaceutical companies. Using patent data from 2005-2018 on brand-name drugs listed in the Federal Drug Administration’s Orange Book, the database reveals the extent of the evergreening strategy used by pharma to prolong patents, often for trivial reasons, and delay the entry of competition, especially generics. The strategy helps drug companies maintain market share and contributes to high drug prices.
