Our Take
DeepIP is assembling European patent market share through acquisition, but the real test is whether a Paris-New York startup can hold Poland, Germany, and Italy against local competitors with existing firm relationships.
Why it matters
European patent prosecution has long-tail, jurisdiction-specific workflows that North American AI tools treat as afterthoughts. PatentMaker's adoption inside Boehmert & Boehmert and across German top-50 IP firms signals where the friction actually lives.

IP counsel at top-50 European firms: evaluate whether PatentMaker's German-native compliance and workflow mapping justify switching from your current tool, or whether DeepIP's speed and scale across 25 jurisdictions matters more for cross-border teams.
DeepIP closes acquisition of PatentMaker
DeepIP, an AI patent drafting platform founded in 2024 by François-Xavier Leduc and Edouard d'Archimbaud, has acquired PatentMaker, a patent workflow tool built by German patent attorney Dr. Matthias Hofmann and deployed across European IP practices. The deal consolidates two complementary platforms: DeepIP's rapid-growth North American base (more than 400 law firms and corporate IP teams across 25 jurisdictions using the platform; 25,000+ patent applications drafted to date) with PatentMaker's entrenched presence in German and European practices (adoption among nearly half of Germany's top IP law firms, plus corporate teams at Infineon Technologies and Siemens AG).
DeepIP raised more than $40 million within nine months of launch and counts more than half of the top 50 North American IP law firms as clients (company-reported). Hofmann, PatentMaker's founder, joins DeepIP as cofounder responsible for Germany. The combined platform is designed to cover the full patent lifecycle: invention capture, prior art search, drafting, filing, prosecution, and post-grant work within a single environment. DeepIP is opening a German office within Boehmert & Boehmert's Munich headquarters, where Hofmann is an equity partner.
European patent practice is structurally different from US prosecution
PatentMaker was built specifically to address the time sinks that slow European practitioners: routine tasks that consume hours per application across different national patent offices and the European Patent Office. Hofmann built the tool out of necessity, for use inside his own firm. That origin story matters because it signals where the product-market fit actually sits.
DeepIP's existing market strength is North American. Expanding into Europe requires more than a translated interface. German patent law, French filing requirements, and UK post-Brexit procedures each have distinct prior art searches, examination timelines, and prosecution conventions. PatentMaker's use inside Boehmert & Boehmert (one of Europe's top-tier IP firms) and adoption across German peer institutions suggests the tool has solved jurisdiction-specific compliance and workflow issues that a US-first platform would treat as edge cases.
The acquisition also signals where DeepIP sees defensible competitive moat: entrenched relationships inside major regional firms, not just feature parity across geographies.
What IP teams should evaluate
For European IP counsel evaluating patent AI platforms, the acquisition creates two decision points. First, whether PatentMaker's German-native compliance mapping and existing workflow integrations inside your peer firms justify staying on the tool versus migrating to DeepIP's broader platform. Second, whether DeepIP's scale across 25 jurisdictions and integration with North American teams creates value for firms handling cross-border prosecution.
Hofmann's move to cofounder status at DeepIP suggests PatentMaker will be integrated into DeepIP's platform rather than run as a standalone product. Teams currently on PatentMaker should clarify migration timelines and feature preservation with DeepIP directly.
