Expired Patents are a Public Good
Patents are valid for 20 years from the initial application filing date. Once a Patent expires the invention becomes a public good. However, if people don’t know of the public good, they are unable to use, capitalize, or employ the invention or design advancement. If only one in five patents are fully commercialized, there exists in this database significant business opportunities.
The BDTwo.com website endeavors to shine a light on some of the inventions which the public owns and has the right to use. This website focuses only on expired patents, using purpose built search parameters to isolate expired patents. We list both the application date and the patent award date for reference. We link to other sites Patent data for corroboration and to ease user’s experience. Some patents were further refined or improved upon, winning subsequent patents and legal protections. We recommend users consult an attorney for legal advice.

Still others use Big Data to make Bewildering Debates Barely Delusional. For a Bemused Diaspora of Bigwig Doers who Base Decisions on Bland Discussions of Blatant Definitions.
