You should be aware of them. They are in the business of helping people find prior art. Article One Partners uses the power of the global online community to research evidence that relates to the claims of novelty of selected patents. A patent, in essence, tells the story of a technology as of a certain date. Its validity is analyzed based in part on whether the same story is told in earlier publications. You can request a study be done by the AOP community for such publications that relate to select patents. These publications, known formally as prior art, are publicly available and may be in any language from anywhere in the world. Article One Partners offers compensation to researchers from 176 countries to help find prior art, and that reduces the risk of infringement assertions by competitors, and improves your patent quality.
