With more comprehensive art citations during prosecution, a patent will be more likely withstand attacks under 35 USC 102 and 35 USC 103. This benefit to the validity of a patent can be maximized when the most relevant portions of each cited reference are made of record and presented to the Examiner for consideration. With deep neural network sentence encoders, highly detailed and relevant pin citations for each art reference can be mapped to each claim element sought during prosecution and provided to the Examiner for consideration. Any resulting patent will be immunized against attack from these or similar references.
