We avail analysis based on different types of years to make your research as precise as possible. The types of years available to choose are prosecution, publication, filing, grant, and case exchange years.
Filing, publication, and grant year are derived from the raw patent data. Filing year indicates when, for example, a law firm was working on a certain filing. The earliest publication date is used for the publication year. The earliest grant date is used for the grant year (available for granted applications only).
Prosecution and case exchange year differ from dates available in the raw patent data. They were created to adjust for shortcomings in the raw data and provide more precise trends.
Prosecution year takes a combination of filing dates and the earliest publication dates. We take the filing date for all priority applications, domestic subsequent, and direct foreign filings, as well as the earliest publication date for regional/national entries of a PCT. This is because for regional/national entries of a PCT, the raw data artificially sets the PCT filing date as the filing date of the regional/national application although the regional/national phase applications are usually filed later. The earliest publication date is hence more accurate for regional/national applications as it gets us closer to the actual time when an attorney worked on submitting the application to an office.
For case exchange year, we take the receiving firm’s filing dates as the best possible estimation of the time when the sending firm sent work to international partners and, therefore, more accurately shows the trend for sent cases.
