On Oct. 9, 2013, Mr.Strub, the inventor of US7,523,166, filed a complaint against YouTube LLC for patent infringement.
The patent in this case is US7,523,166, titled “Method and device for message broadcasting enabling the recipient to retrieve at least partly a message”, granted on 4/21/2009 to Strub.
The '166 patent relates a method and system for broadcasting messages of an advertising natural which ensure that a recipient of the advertising message takes into account at least a portion of the content of the message. The method and system prevent a user from skiiping or advancing through an advertising message during at least a period of delay.
The plaintiff alleged that YourTube utilizes a method and system for broadcasting messages of an advertising natural which ensure that a recipient of the advertising message takes into account at least a portion of the content of the message in a manner that infringes at least claim 2 of '166 patent by utilizing the features described in paragraph 10-13 on at least its services.
'166 has 6 family members but no any equivalent Japanese application. The technical field of '166 is listed as IPC subclass G06Q30/00, H04M3/533. Japanese patent documents are very rich source or prior art in this technical field. In a preliminary Japanese patent search using following search string: (G06Q30/00 OR H04M3/533 AND 20010510), we got 5511 hits. If we add a Japanese keyword "koukoku" that corresponds to "advertisement" in English as a filter to remove search noise, we got 324 hits.
As can be seen from the machine translated titles of the 324 hits, these Japanese patents are all references of advertising methods over internet.
