Recent Client Success Story

New York patent attorney spent over $15,000 on unsuccessful searches. When he contacted us, we offered him the Silver Bullet invalidity search where he would only pay minimum amount (and not the complete fee) if no killer art is found – irrespective of how extensive effort we put. In 10 days, we got him one 102 patent prior art, two 103 patent prior art and one 103 non-patent prior art. He gladly paid $6,999, said he should have come directly to Sagacious IP – and now orders Silver Bullet searches on all cases.
