Three10 Solutions, Inc. d/b/a DorothyAI


DorothyAI was founded by patent lawyers with nearly 50 years of combined experience who saw the value of patent searching and knew there was a better, more secure way to find relevant patent information than outsourcing. We use cutting edge natural language processing and machine learning to query the world’s patent database and identify relevant patent publications using an intuitive user interface.

Our mission is simple: produce affordable and efficient patent search products that work for practitioners, save outsourcing costs, and give time back to practitioners to work on high value projects that generate profits and impress clients. We are committed to producing user friendly products, and providing excellent user support to back them up.


Pricing is based on contract type (i.e. length,individual or bundled products) starting at $50 per user per month for accessto the basic DorothyAI patent search platform.

Included Data

Global Patent Data


Natural language processing

Machine learning



Methods Used

The platform uses an ensemble of AI algorithms and more traditional search models including:

●     Natural language based search queries are deconstructed using a natural language processing(NLP) model and plotted against the world’s patent literature.

●     Machine learning algorithms are used to index the patent database and compile a thesaurus ofsynonyms that is constantly updated. Words in the query are tokenized and replaced with all or a subset of synonyms based on user input via a slide bar.

●     Every query isclassified based on the collaborative patent classification (CPC). Our classifier is better than any published classifier to date.  

●     Returned results from each of the ensemble of search models are processed to remove duplicates,assign a relevancy score to each reference by comparing the references to search query, and order the references by relevance before they are returned to the user interface.

●     An NLP model identifies “Key Phrases” from the text of each document and returns these results to the user interface.

●     Advanced Filters uses an NLP based model to weight phrases, sentences, and paragraphs in returned references that include specific “Facet Terms,” and reorder return results based on their use of selected facet terms and, in some cases, synonyms of the selected facet terms.
