Among these patents is U.S. Patent No. 6,275,802, which describes an improvement to automatic speech recognition techniques. The patent claims a search algorithm for decoding recognition hypotheses using a more efficient forward-backward search.



PDF icon Matrix Controlled Expert System Producible from Examples (PDF: 1.5MB)
U.S. Patent No. 4,730,259
Stephen I. Gallant

Patent 4,730,259

At the time it was filed, this patent represented both the legal and technical cutting edge in the computer software field. The patentability of software had not yet been clearly established. This patent has appeared on a short list of the very first patents in the field of expert systems.


PDF icon Apparatus and Method for Graphical Display of Statistical Effects in Categorical and Continuous Outcome Data (PDF: 2.4MB)
U.S. Patent No. 5,452,410
SI Software Limited Partnership

Patent 5,452,410

Even a straight line graph can be patented if the function producing the graph is novel and inventive. This patent concerns the representation of statistical effects of different conditions on a categorical or continuous outcome. This patent, which is heavily computational, was issued long before the State Street Bank decision made clear that such subject matter was patentable.



ELECTRICAL

PDF icon Home Interface Controller for Providing Interactive Cable Television (PDF: 2.6MB)
U.S. Patent No. 6,100,883
ICTV, Inc.

Patent 6,100,883

Bromberg & Sunstein has prosecuted a portfolio of patents devoted to the emerging industry of interactive television. Our client ICTV has developed technology that enables cable television subscribers to receive video programming that allows them to interact with their television to play games, videos, and music on demand; browse news, sports and weather; and view targeted interactive advertising.



PDF icon Switch with Programmable Delay (PDF: 2.4MB)
U.S. Patent No. 5,955,910
