A group of bi-partisan Senator Susan Collins plan to unveil today a
bill
requiring drug makers to disclose the patents they hold. The legislation is meant to shine a light on “patent thickets,” when drug makers get numerous patents around a single product to make it harder for other companies to create low-cost generic versions. The proposal wouldn’t change the patent system or forbid the practice in any way, but would create a searchable database of drug patents.
Advocates for changing the patent system say such a change would be a small but important step to enhance transparency of biologic patents. Patent law is increasingly becoming central to the discussion around drug pricing in Congress.
Companies including AbbVie Inc. have come under scrutiny for their patent strategies. That company has more than 100 patents around its best-selling drug Humira, a treatment for inflammatory diseases such as rheumatoid arthritis and psoriasis.
