Short answer: Yes — R&D staff should sign a separate IP assignment agreement beyond the labour contract, not because a labour-contract clause is worthless, but because the separate agreement does four things a short labour clause cannot: it defines exactly what is assigned, handles creations made before joining, states a transparent author-remuneration mechanism, and sets filing-cooperation duties that survive the employee’s departure. The more key the staff member, the more indispensable this agreement is.
Legal basis
The legal foundation exists: the IP Law provides the rights mechanism for inventions and works created in employment (rights vesting in the investing organisation/employer under the statutory mechanism, with the author keeping moral rights and entitled to remuneration as regulated when the invention is exploited), and the parties may agree the detail in writing. Labour contracts are constrained by the Labour Code’s employee-protection rules and short standard clauses; the separate IP agreement is a specialised civil contract allowing depth on present and future assignment, off-hours and off-duty creation, and the duty to sign filing papers — exactly the points where companies’ title chains break in practice.
How this applies in practice
What a standard-grade separate assignment agreement must contain: (1) a definition of ‘creative results’ covering patents, utility solutions, designs, software, secrets and technical data created in-duty or with company resources; (2) a present assignment of future results, so rights pass the moment a result is created, plus a duty to sign all papers needed for domestic and foreign filings, surviving the end of employment; (3) a prior-inventions list declared by the employee — undeclared items fall inside the assignment, declared items are cleanly carved out; (4) the author-remuneration mechanism under the legal rules and the internal bonus policy, with figures and payment timing stated clearly so it never becomes a dispute; (5) confidentiality and document return on exit; (6) treatment of off-duty creation — a fair boundary between company rights and the engineer’s personal creative life, because a greedy clause grabbing unrelated creation destroys signing goodwill and the clause’s own credibility.
The separate agreement is ‘worth more’ than a labour-contract clause in three practical senses: depth of content (a labour contract cannot hold the above), durability after departure (filing-cooperation and secrecy duties written to survive independently), and evidentiary value in investment due diligence — investors reading the core R&D team’s separate agreements score the title chain directly upward, while a single labour-contract line usually triggers a demand to re-sign everything before funding. Re-signing current staff is entirely feasible when paired with proper communication and a fair remuneration policy attached.
Action checklist
- Draft a separate IP assignment agreement for all R&D staff, core group signing first.
- Include present assignment of future results plus filing-cooperation duties surviving departure.
- Have employees declare a prior-inventions list for a clean carve-out from day one.
- State the author-remuneration and invention-bonus mechanism with concrete figures and timing.
- Store signed agreements centrally with personnel files, ready for investment due diligence.
Risks and practical notes
An over-greedy assignment clause — grabbing every employee creation including off-hours, unrelated fields, unlimited in time — is a cultural and legal risk at once: it makes good engineers reluctant to sign and to disclose inventions, and it can be judged unbalanced in a dispute. The opposite operational risk is signing the agreement but never operating it: no disclosure forms collected, remuneration paid late, no updates when roles change — then the separate agreement is just one more sheet in the file instead of a living rights system.
Frequently asked questions
Should R&D staff sign a separate IP assignment agreement?
Yes, especially key R&D staff: the separate agreement defines what is assigned, handles prior creations, states the remuneration mechanism and sets filing-cooperation duties surviving departure — things a short labour clause cannot do.
Is a separate agreement worth more than a clause in the labour contract?
More in depth of content, durability after employment ends, and evidentiary value in investment due diligence; but it supplements rather than replaces the statutory rights mechanism and the base labour-contract clause.
What must it contain?
A definition of the assigned creative results, present assignment of future results, a prior-inventions list, the author-remuneration mechanism, the duty to sign filing papers, confidentiality and document return, and the off-duty creation boundary.
