Many compact digital still cams can record tone and moving movie as well seeing that still photographs. Almost Patent Draftsman are digital.

In a patent litigation relating to a digicam, prior skill search is usually performed. The almost all important source of prior art regarding digicams is Japanese prior art documents. Japan is the particular leading country in digital camera growth since early of 1990s

As can easily be seen in the table below, you will discover about 10, 500 patent documents posted annually in Western that contain typically the word of “digital camera” in Western. For details, you should refer to Western patent search. Since there are so many Japan patent documents submitted in the area of digital digicam since 1993, browsing Japanese patent paperwork for a certain feature of a digital camera is a challenging job.

When performing a patent search, we recommend to work with a combination involving full text queries (broad search) plus classification searches (focused search) approach.

Electronic digital cameras are private into the using fields in Japan patent system:

Throughout a validity lookup for a particular litigation for a new digital camera, often classification searches are widely-used if the feature(s) of any target digital camera is properly defined. Yet , a good examiner may miss-classify a patent, consequently, we recommend employ a broad, entire text search along with key word guitar strings besides the classification search. When using the combination involving classification search and full text research, we are able to locate and even uncover pertinent skill, if there is usually a pertinet artwork.
