2.19.1.10 Additional to an Additional

Date Published

A patent of addition may be applied for, and granted, in respect of another patent of addition (see McFeely's Application (1912) 29 RPC 386). There is also no objection if there is a longer series of additional applications. However, it is essential that the patent request discloses all relevant facts, such that the term of any patent issued can be readily determined.
