The law firm creates the case
You open an invention case without your client having to be a paying customer first. The client receives approved, free viewer access.
Patent law firms
Client and law firm in the same case.
Clients and patent attorneys work on the same invention case. You do not start with a stack of documents, but with a technical model of the invention that you review and develop further together.
Market launch Q4 2026 Collaboration with law firms starts at market launch in the fourth quarter of 2026; the full law firm package follows afterwards.
Two ways into the same case.
The client invites the law firm
Anyone who has already worked out an invention in ErfinderWerk invites their law firm. Review, revision, questions and versions all run in the same case.
The technical model, not just a document.
Features, working principles and alternatives are building blocks that you can follow and comment on, instead of reading them out of running text. The technical groundwork is fully available to you: visual invention workspace, features, draft claims, figures and description.
Review, approvals and versions.
- Technical review with comments and questions directly on the feature.
- Structured claims and description, supporting research and figures as the basis for your drafting.
- Roles and versions: you see who changed what and which state is approved.
- Case and team management for your law firm, export to prepare the filing.
Viewers, credits and cost bearers.
Free client viewer
The client sees the approved file, versions and status. Editing and their own AI actions are not part of the viewer role.
Credit pool and cost bearers
Your law firm maintains a credit pool. Every AI action has a named cost bearer; cost approvals are explicit.
No double charging
If an invention moves from the client to the law firm or vice versa, it is not charged twice. A company can contribute credits after approval by its administration.
The features overview explains the viewer as a role, not as a separate plan.
Responsibility stays with you.
The AI takes on no attorney responsibility and guarantees neither patentability nor patent quality. Examination, advice and filing remain your task. Access to ErfinderWerk does not create a mandate; the formal mandate remains a separate agreement between client and law firm.
On confidentiality: data sheet, confidentiality commitment and the page AI and data protection. The directory of experts is described on the page Expert network.
Variants.
| Variant | What is included |
|---|---|
| Starter | For small law firms: mandate workspace with review and free viewer for clients. |
| Pro | For law firm teams: team roles, several mandates and reviews, cost bearer selectable per mandate. |
| Team | For larger law firms: shared client workflows and administration tools. |
Law firm profile on the same technology as the invention workspace, billed annually by invoice. Clients follow along for free. Exactly one cost bearer pays for each AI action: the law firm or an approved client budget.
We will announce prices and terms at market launch. AI usage is billed separately through credits.
Frequently asked questions.
Can my law firm use ErfinderWerk today?
The entry point is aimed at individuals. Controlled collaboration with law firms is part of the market launch; the full law firm package follows afterwards.
Who bears the costs when the client works along?
Every AI action has a named cost bearer. As a viewer, the client does not trigger any paid action.
Does this replace law firm software?
No. ErfinderWerk prepares the technical invention and makes it editable together. Deadlines, files and filing remain in your systems and under your responsibility.
