Re: forward citation (Families)

Hello Manual, the purpose of the limitation on a time frame for forward citations is to avoid bias. In simple words: patents that were published in 2010 will have had more opportunity to become cited then a patent application that was published in 2017. Therefore researchers look at the date of publ...

Re: forward citation (Families)

Re: Gap betweeen US patent counts & DocDB simple family counts

Hello Thomas, this is due to the endless series of (US) divisional applications originating from 6 "parent" US applications. The process to assign DOCDB_FAMILY_IDs takes into account not only the so called Paris Convention priorities but also the data in TLS2016_APPLN_CONTN and TLS205_TECH_REL. Have...

Re: patent citation (backward citation)

Hello Devor, your observation is correct, but if you do a family-family analysis, then you have to give your data preparation a serious thought on what attributes you will migrate to family level, and more important how you will do that for attributes that are "application" bound. Very specific: how...
