when does a patent application become prior art
Prior art To anticipate the subject-matter of a patent claim, prior art is generally expected to provide a description sufficient to inform an average worker in the field (or the person skilled in the art) of some subject matter falling within the scope of the claim. Prior art must be available in some way to the public, and in many countries, the information needs to be recorded in a fixed form somehow. Prior art generally does not include unpublished work or mere conversations (though according to the European Patent Convention, oral disclosures also form prior artâ€”see Article 54(2) EPC). It is disputed whether traditional knowledge (e.g., of medical properties of a certain plant) constitutes prior art.[citation needed]
Inventors' Day In recognition of the enormous contribution inventors make to the nation and the world, the Congress, pursuant to Senate Joint Resolution 140 (Public Law 97 â€“ 198), has designated 11 February, the anniversary of the birth of the inventor Thomas Alva Edison, who held over 1,000 patents, as National Inventors' Day.
