DeepIP enters German Market by acquiring PatentMaker
AI patent software provider DeepIP has gained a foothold in the German patent prosecution market. Today, the company announced the acquisition of its Munich-based competitor, PatentMaker. With this move, DeepIP – which has a particularly strong presence in North America – is also driving forward its expansion in Europe.

PatentMaker is predominantly used for patent prosecution and drafting. The AI tool was originally developed in collaboration with IP law firm Boehmert & Boehmert, specifically by Matthias Hofmann, a patent attorney and equity partner at the German patent firm.
According to PatentMaker, the tool is currently used by around half of the leading German IP law firms, including major patent firms such as Bardehle Pagenberg, Maiwald, and Vossius, as well as a number of major German corporations, such as Infineon Technologies and Siemens.
Now, AI platform DeepIP has acquired PatentMaker in its entirety. Following the deal, DeepIP will operate an office in Munich with the aim of becoming a leader in AI patent drafting and prosecution in Europe.
New York, Paris and now Munich
DeepIP, founded in 2024 by François-Xavier Leduc and Edouard d’Archimbaud, has acquired PatentMaker to consolidate its position in the European market for AI-supported patent drafting and prosecution. Through PatentMaker, it gains access primarily to Germany, the largest patent market in Europe.
Based in New York and Paris, DeepIP recently secured a further $25 million in funding. The company has raised more than $40 million since its launch. The money was invested primarily by venture capitalists.
According to DeepIP, the platform is used by over 400 law firms and corporate IP teams across 25 jurisdictions. The company says more than 25,000 patent applications have been drafted on the platform to date, with clients including Greenberg Traurig, Mewburn Ellis, Jacobacci & Partners, Dexcom, and Philips.
The combined offering is intended to cover the full patent lifecycle, from invention capture and prior art search through drafting, filing and prosecution to post-grant work.
Munich office at Boehmert & Boehmert
As part of the transaction, DeepIP is establishing its German office within Boehmert & Boehmert’s Munich premises. Celia Jinlan Wei, co-founder and managing director of PatentMaker, will lead the German business.

Wei joined PatentMaker as managing director in 2024, having previously spent nearly six years at Munich-based patent firm Prüfer & Partner.
Boehmert & Boehmert partner Matthias Hofmann joins DeepIP as co-founder responsible for Germany. He developed PatentMaker as an internal tool at Boehmert & Boehmert to handle routine patent work, before it was rolled out to external users.
Boehmert & Boehmert was an early adopter of PatentMaker and continues to position itself as a reference partner. The firm does not have a stake in PatentMaker, however.
A competitive European market
DeepIP CEO Leduc described Germany as “the innovation powerhouse of Europe” and pointed to PatentMaker’s embedded position in practitioner workflows as a key rationale for the deal. Hofmann said the partnership was intended “to bring together the strengths of two proven solutions into one unified platform”.
With the acquisition, DeepIP is now making its mark on the German market, in which several providers such as Solve Intelligance or Qthena are competing to establish AI tools in patent drafting and prosecution workflows.
