What is a patent family?
Patent families are a single invention that is protected in a number of different countries. They all have a common date that the invention is protected from (the "priority date"). Each family is made up of a number of applications and grants from each of the counties that make up the family.
Cipher’s applies the DOCDB EPO definition of a patent family.
To account for the fact that a family consists of multiple patent rights in multiple geographies the patent family status is derived as follows:
- If the family includes a member in a major geography (US, EPO, Germany, UK, Japan, South Korea), it will be considered granted when the first patent in any major geography grants.
- If the family does not include a member in a major geography, it will be considered granted when the first patent in any geography is granted.
What is a 'priority date'?
Priority date is the date the first patent application in the patent family was filed.
What is Cipher's definition for a patent family status?
• Pending – Patent family is actively being prosecuted, but is not yet granted (is still an application).
• Granted – Patent family is granted and in force (i.e. renewal fees have been paid).
• Rejected – Patent applications that have been successfully opposed, rejected by the relevant patent office, or are more than 20 years since their priority date, so could not proceed to grant.
• Expired – Patent families which were granted, but have now expired either due to age (the maximum life of a patent is 20 years, with few exceptions). Or non-payment of renewal fees.
• Inactive – Patent family has not yet granted, and has seen no activity on any of the regional or national applications for over five years.
