Two tools for different tasks
DeepIP's product pages describe modules for drafting applications, for prosecution, for searching, and for freedom-to-operate and patentability analyses. These are the provider's statements on its feature set, not independent proof that the results are professionally correct.
| Biwak | DeepIP | |
|---|---|---|
| Built for | General office tasks: reading and analysing files, creating new files such as CSV tables or HTML pages. | Patent work: complete draft applications from invention disclosures, responses to office actions with case-law references, searches and analyses. |
| Patent data | No patent database; practically no web search in the desktop app. It works with your files. | Semantic search in a patent collection, according to the provider. |
| Working environment | Desktop app for macOS and Windows with a chosen working folder. | According to the provider, the prosecution module works directly in Microsoft Word. |
| Data | Model requests go to Microsoft Azure in the EU Data Zone; only if Azure declines do they go to PREM SA in Switzerland, which, according to Prem, has them processed at Nebius and TensorX in the EU and the United Kingdom. DPA for businesses at biwak.ai/avv. Details. | According to the provider, storage on Microsoft Azure in the USA or the EU, depending on the customer's location; no training on customer data. |
| Price | Subscription at €19 for one person or €99 for the whole team, cancellable monthly. Plans. | No price stated. Ask for a quote and a trial with your own professional tasks. |
What DeepIP does better
For the actual patent work, DeepIP brings specialist workflows that a general agent does not have:
- From invention disclosure to application: the provider describes complete draft applications tailored to the relevant jurisdiction.
- Office actions: rejections are analysed and structured responses with case-law references are drafted, directly in Word with comments and track changes.
- Search and analyses: patent search, freedom-to-operate and patentability are separate modules; Biwak has no patent database and works with your files.
Consider DeepIP for drafting and defending patents, and Biwak for the office work around them. With both, unpublished inventions should only enter the workflow after a review under professional rules; what § 39c PAO (German Patent Attorneys' Code) requires for this is explained in the article AI in the law firm.
Test case: a draft application from a published invention
For the test, take an invention that has already been published, so that the material contains no secrets. Have DeepIP produce a draft application from it and draft the response to a closed office action. From Biwak, ask only for what a general agent can deliver: a table of the features with references from your documents, or a deadline list from a case file. A patent attorney evaluates both results and notes the correction effort; only then is a test with real client material worthwhile.
Basis of this comparison
This comparison was written by Biwak, i.e. an interested party; we have not checked DeepIP's professional quality. The information on DeepIP comes from deepip.ai and the product pages on drafting and prosecution, retrieved on 23 September 2026. We have not tested either tool on patent material; the test case above is a guide for your own trial. Please report errors to kontakt@biwak.ai.
Frequently asked questions
May an unpublished invention go into an AI tool?
Only after a review. § 39c PAO requires a contract in text form with a confidentiality obligation for service providers and, for services abroad, comparable protection of secrets. The Federal Association of German Patent Attorneys points out that publication destroys novelty and anonymisation does not help, because the technical core is the secret. The DPMA (German Patent and Trade Mark Office) itself currently only uses internal AI applications for unpublished applications (FAQ on Communication No. 1/26).
Does Biwak replace specialised patent software?
No. Biwak promises neither a patent database nor an expert patent review. For draft applications and office actions, a specialist tool is the right category; Biwak helps with the office tasks alongside.
What should you look out for in a pilot for patent work?
Approved or published material, acceptance by a qualified person, and the correction effort per result. Check whether source references are correct and the draft is technically complete. A general file test is not enough for this question.
