Message from the founder
Why I built ClaimMark-P
I have spent more than thirty years building enterprise software that cannot afford to be wrong. At Random House I led the team that built the world’s largest SAP module of its time, and for years I taught SAP’s own curriculum for SAP America and SAP Canada.
Patent attorneys, in-house and in private practice, came to me with the same complaint. The AI tools they had tried were black boxes. They produced confident text that the attorney could not check, so the time saved in drafting was lost again in verifying it. I asked them to list what they needed, and every problem they had hit with the tools they used.
ClaimMark-P is built from that list. It helps attorneys prepare patent applications and respond to Office Actions efficiently and correctly, and it is completely transparent. There are no black boxes: every claim element, paragraph, and citation traces back to its source, so the attorney can verify every result. Attorneys keep reviewing it, and their needs decide what we build next.

Why I built ClaimMark-P
I have spent more than thirty years on every side of patents: drafting and prosecuting them, licensing them, and defending portfolios when they were challenged. The lesson has always been the same. A patent is only worth what survives the examiner, and then what survives a court.
Most AI drafting tools are built to produce a draft quickly. ClaimMark-P is built to produce a draft that holds up. Before a draft reaches you, it has been attacked the way an examiner would attack it, checked against §101, §102, §103 and §112, and strengthened where it was weak. Every claim is traced back to its source, so you can see why the draft says what it says instead of having to trust it.
I am a co-founder of ClaimMark, so I am not a neutral judge of it. That is why we are publishing our benchmark method, code and samples, and inviting other patent attorneys to check our work. I would rather be proven right in public than asserted right in marketing.
The judgment stays with you. ClaimMark-P does the reading, the checking and the first drafting, so you can spend your time on the decisions only an attorney should make.

What we believe
The attorney decides
ClaimMark-P assists qualified practitioners. Legal judgment, signatures, and filings stay with counsel.
Show the work
Every claim, paragraph, figure, and argument traces back to its source. If it can't be supported, it is flagged.
Software first
We launch where we have validated the output: software, AI, cloud, cybersecurity, and data-processing inventions.
Evidence over slogans
We describe what we have measured, and we say "internally validated" until customers and independent attorneys confirm it.
About Wanda and Milo
Wanda is a patent attorney who does magic on the side; Milo is the associate who always ends up holding the files. They're fictional characters, and they're here to make a point: real magicians never reveal the trick. ClaimMark-P shows you every one.
