How different does a patent have to be to not violate patent law?
My understanding there is no formula, such as a 20 percent difference being enough to avoid infringement. Instead, inventors should follow the requirements of distinctiveness: being novel and non-obvious
To qualify for a design patent, the subject must be new in the sense that no single, identical design exists in the prior art, it must satisfy the ornamental standards, and it must be original to the inventor or inventors seeking protection.
Apparently, the patent description should include everything that makes your invention new. It must also include the information necessary for an average person to make your invention. Together with the claims component, a patent description is known as the specification
So PVDM and others at BRN have already registered patents and continue to register new patents with our patent lawyers expert advice etc and the Akida patents can be obscure enough and lack detail to not give away the secret sauce of Akida, then it appears the patent must also include the information for an average person to make your invention.
Who is this average person? Lol
Note - I’m sure Diogenese and FACTFINDER may have a very logical answer as a reply to the above.
