Patentability
• USEFUL
– useful purpose – operativeness (invention must serve purpose)
• NOVEL (new)
– Not known or used by others – Different from prior art – Not patented or publicly disclosed previously 1 year grace period in US and Canada most other jurisdictions have absolute novelty requirement
• Non-OBVIOUSNESS
– “sufficiently different from what has been used or described before that it may be said to be nonobvious to a person having ordinary skill in the area of technology related to the invention”

Patentability can be difficult to determine
• May need expert analysis or opinion • Negative patentability assessment saves$
– Can refocus work to decrease risk – Can abandon risky/non-patentable research

Patent Myths
• Patents are all valuable
– <2% of patents have commercial value
• Patented inventions are verified by the gov’t • Provisional patents are valid for 1 year
– Sets priority date, need to convert to regular appl
• Provisional patent applications just need to describe the concept
– Need to enable the invention, claims useful
• You can patent an idea • A patent can be enforced for 20 years
– Issuance to expiry: 17 years in US

Myths, con’t
• A patent give the owner the right to make, use, sell the invention
– Gives enforcement rights
• A US patent is honoured world-wide
– Jurisdiction specific
• A patent protects an invention
– Owner must enforce rights
• The first thing you should do on getting an inventive idea is file a PATENT
– Save your money, don’t disclose, use CDAs, keep good records, make a business decision to file

Review patents or potential interest
• Browse titles, view lots of documents • Use classification and search within sub/classes
– Link to classification list (P) – Link to published applications (A)
• Use html display of individual patents
– “find” keywords in text
• Use IMAGE (tiff viewer) to print • If extra large docs, buy from micropatent

Tips
• Patent searching is iterative (how invention works) • Patent language and classification is difficult
– Legal, technical, merely descriptive (keywords may be useless) – "Four rectangular uprights supporting a planar surface" describes a table
• • • • • •
Search published applications and issued patents Search broad date range (within reason) Search USTPO, CIPO and EPO Use ESPACENET if your keywords are good Search classifications using keywords Keep a list of terms, classes searched
