Patents
- Patents are about functional and technical aspects of products and processes.
- Most patents are for incremental improvements in known technology - evolution rather than revolution.
- The technology within a patent does not have to be complex.
- A patent gives an inventor the right, for a limited period, to stop others from making, using or selling an invention without their permission.
- The inventor is allowed a short term monopoly in return for allowing the invention to be made public.
- Patent rights are territorial; a UK patent does not give rights outside the UK. If you want rights to extend outside the UK you must apply for those rights.
- If the invention is made in a foreign country, the entitlement laws of that country apply.
- A patent usually lasts 20 years and is kept active by paying annual fees.
- The patent holder can prevent anyone else from using the technology but it doesn’t give automatic right to use oneself.
- Some patents, such as those for medicinal products, may be eligible for a further 5 years protection with a Supplementary Protection Certificate.
To be patented, the item:
- Needs to be novel.
- Needs to contain an "inventive step".
- Needs to be non-obvious to "one practised in the art".
- Needs to be capable of industrial application.
- Must not be "excluded".
- For everywhere except the USA, needs to be secret at the time of filing i.e. "not in the public domain"
Patents - Ownership
- The principles surrounding entitlement (the right to apply for and own a patent) are not straightforward.
- Starting presumption is that the right to apply for and own a patent for an invention belongs to the inventor or inventors.
- This right can be over-ridden if inventor gives or sells his rights to someone else, or by virtue of law in the country in which the invention is made.
- If the invention is made in the course of an employee’s duties, the invention belongs to the employer if:
- it was reasonable to expect an invention to result from the employees duties (for example, if they are employed to carry out research and development), or
- the employee had a special obligation to further the employer's interests (for example, as a company director).
Disputes can arise over who is really the inventor, or whether the inventor was an employee when the invention was made.
Patent - Uses
- A patent provides owner with means of stopping others - doesn’t have intrinsic value, still need to license the technology.
- The patent can be the foundation of a spin-out company or licenced to other companies. The inventors can share in the royalties from the patents.
