The Ocean Tomo Ratings systems are the most advanced web-based patent data, ratings and analysis platforms designed for objectively assessing patent quality, relevant patents, competitive technologies, and related trends. From individual patents and patent portfolios, to technology sectors and companies, the Ocean Tomo Ratings systems provide unparalleled strategic insights and analysis.

The Ocean Tomo Ratings systems are part of a global platform which will include patent analytics for each of the five major patent issuing organizations. Since 2005, Ocean Tomo has been a leader in providing ratings for U.S. patents (OTR-USPTO). Separate ratings for all patents issued by the EPO (OTR-EPO) were completed at the beginning of 2014. In 2015 OTR-SIPO was introduced. The firm anticipates introducing additional Asian based ratings in 2015-2016.
