The USPTO Patent Assignment Search (Beta) API allows developers to retrieve patent assignment information from USPTO's assignment search database and generate XML files with the search results. These files contain lists of found documents and their categorization. This API is provided by the United States Patent and Trademark Office (USPTO) as part of their Open Data Portal.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
