On February 5, the USPTO reached an important patent document milestone: the two millionth published application. The first US application (2001/0000001) was published almost eight years ago on March 15, 2001. The USPTO published 6,581 applications on Feb. 5. Depending on how you count (including or not including withdrawn published applications), the two millionth published application could be 2009/0035278, Reoviruses Having Modified Sequences, or 2009/0033321, Rotational Angle Detection Device.
The inventor listed on the first application is Matthew Coffey of Calgary, Alberta. The assignee is Oncolytics Biotech, Inc., also located in Calgary. Reoviruses are used to treat disorders where cells proliferate more rapidly than normal tissue growth, ie. cancerous tumors, in mammals. The inventor on the second application is Takeo Kurihara of Tokyo; the assignee is Tokyo-based Tomen Electronics Corporation. Kurihara’s invention is related to devices used in magnetic sensors. Tomen has filed PCT and national applications on this technology in the US, Japan, China and Europe.
As of March 1, 2009, according to the USPTO website, the AppFT database now contains records for 2,021,756 published utility and plant patent applications.
