Employee Invention Rewards: Preventing Ownership Disputes with Former Staff

Many founders view patents as a purely technical or legal hurdle, something to be cleared with the patent office and then tucked into a drawer. But a patent is also a property right, and like any valuable property, its title can be contested. In my twenty years of practice, some of the most damaging hits to a company’s valuation didn't come from competitors—they came from within, specifically from former engineers who felt they weren't fairly compensated for their "Employee Inventions."

The patent ownership on your filing receipt is only as strong as the reward system that supports it. Under Chinese Patent Law and similar global frameworks, while the employer generally owns the rights to work-related inventions, the inventor has an inalienable right to "remuneration" (rewards and compensation). Failing to define this in a written agreement means falling back on statutory defaults that are often expensive, rigid, and prone to litigation once an employee walks out the door.

The "Service Invention" Trap: Who Actually Owns the Tech?

The first mistake business operators make is assuming that because they paid the salary, they automatically own every thought in the employee's head. Legally, we distinguish between a "Service Invention" (职务发明) and a non-service invention.

According to Article 6 of the Chinese Patent Law, an invention is a service invention if it is made:

1. In the course of performing the employee's own duties.
2. In the execution of any task assigned by the employer.
3. Mainly by using the material and technical means of the employer (equipment, funds, raw materials, or internal technical data).

The risk often intensifies after an employee leaves. If a former staff member files a patent within one year of resignation, and that patent relates to their previous duties at your company, the law still classifies it as your service invention. However, if your internal records are messy, proving that the invention resulted from their "previous duties" becomes a high-stakes evidentiary battle.

Statutory vs. Contractual Rewards: The Cost of Silence

If you do not have a specific internal "Reward and Remuneration Policy," the law steps in with its own price tag. In China, the Implementing Regulations of the Patent Law provide a default "statutory minimum" that can be surprisingly high for a growing startup.

The Default Penalty for Silence: In the absence of an agreement, the statutory reward for a granted invention patent is at least 3,000 RMB. More importantly, the ongoing "remuneration" must be at least 2% of the after-tax profits derived from the patent (or 10% of the licensing fee if you lease the tech out).

For a product generating millions in profit, that 2% "statutory floor" can become a massive liability. However, the law allows for "Agreement Priority." This means you have the right to define your own reward structure—provided it is reasonable and follows a specific democratic procedure (such as employee consultation).

In the filings I’ve handled, companies that proactively set a fixed reward—say, a specific bonus upon filing and another upon grant—effectively "contract out" of the unpredictable percentage-of-profit model. This provides the business with financial predictability and the employee with immediate, tangible value.

Three Pillars of a Litigation-Proof Remuneration Policy

To prevent a disgruntled former employee from clawing back ownership or demanding back-payments, your HR policy needs to address three specific areas:

1. The Trigger Events: Clearly define when a reward is due. Most robust policies use a "Three-Stage" approach: a small bonus at the time of internal disclosure/filing, a larger bonus upon the patent being granted, and a potential (but capped) bonus if the patent is actually commercialized.
2. The Calculation Method: If you choose not to use a fixed sum, you must define "profit" with surgical precision. Does it mean gross revenue? Net profit? Only the portion of profit attributable to that specific component? Leaving this vague is an invitation for a forensic accountant to dismantle your books in discovery.
3. The "Full and Final" Clause: Ensure that your payment documentation states that the reward is the "full and final remuneration" for the specific invention. This prevents the "double-dipping" scenario where an employee accepts a bonus but later sues for a percentage of sales.

Lessons from the Courtroom: Why "Reasonableness" Matters

Recent judicial trends in IP courts show that judges are increasingly protective of inventor rights. In several high-profile cases, even when a company had a signed agreement, the courts found the reward to be "unreasonably low" (e.g., a few hundred RMB for a patent worth millions) and adjusted it upward.

The takeaway? You cannot use a contract to effectively "zero out" an inventor’s rights. The court looks for a "reasonable" balance. If your policy was discussed with the staff, published in the employee handbook, and pays out a meaningful amount relative to your industry, it is much harder for a former employee to challenge it.

A Checklist for Founders and HR Managers

Before your next R&D cycle, run your current setup through this filter:

• The One-Year Rule: Do your exit interviews explicitly remind departing engineers of their ongoing obligation to disclose inventions related to their work for the next 12 months?
• The Paper Trail: Can you prove the employee used company "material and technical means"? Keep logs of server access, lab equipment usage, and project assignments.
• The Signature: Do you have a signed "Confidentiality and Invention Assignment Agreement" for every single person who touches your code or hardware?
• The Policy Receipt: Did the employee sign an acknowledgment that they have read and accepted the Patent Reward and Remuneration Policy?

Whether a patent is ultimately granted depends on the technical substance of the R&D and the examiner’s search, but whether you own that patent securely depends entirely on the strength of your internal HR contracts. Don't let your most valuable IP walk out the door in a cardboard box.

Frequently Asked Questions

Q1: If an employee invents something on their own time at home, do I still own it?

It depends on the "Service Invention" definition. If they used your proprietary data or if the invention is directly related to the specific tasks you assigned them, you likely own it. If it is completely unrelated to your business and they used zero company resources, it is likely their private property. The grey area in between is where most lawsuits happen, which is why "duty descriptions" in employment contracts are vital.

Q2: Can we replace cash rewards with stock options?

Generally, yes. Equity or options can be considered a form of "remuneration." However, you must explicitly state in your policy that the equity grant is intended to satisfy the statutory requirement for patent rewards. If the stock plan is silent on patents, an employee might argue the stock was for "performance" and the "patent reward" is still outstanding.

Q3: What happens if I forget to pay the reward for a few years?

The statute of limitations for these claims usually starts when the employee "knew or should have known" their rights were violated—often when the patent is granted or when they leave the company. Late payment is better than no payment, but consistent, timely rewards are your best defense against a "bad faith" claim.

Q4: Does this apply to contractors or "consultants"?

The "Service Invention" rules in the Patent Law specifically refer to employees. For third-party contractors, ownership is governed by your "Work for Hire" or "Development Agreement." Without a written clause stating that the contractor assigns all rights to you, the law often defaults to the contractor owning the IP, with you only having a license to use it.
