At last! A decision on employee compensation for patented inventions (IP/IT newsletter, July 2009)

In the first reported decision concerning compensation of employee inventors under s. 40 of the Patents Act 1977 (the 1977 Act), the High Court has awarded damages and provided guidance on compensation provisions under the 1977 Act. In light of this decision, companies engaged in R&D should consider methods for fairly rewarding outstanding contributions made by employee inventors. They may, however, take comfort in the judge's conservative approach to calculating compensation.

Legislative uncertainties in the 1977 Act

S. 40 of the 1977 Act gives an employee the right to seek compensation from their employer under certain circumstances.

_________________________________________________

S. 40 provisions

  • the employee has made an invention belonging to the employer for which a patent has been granted;
  • the patent is of "outstanding benefit" to the employer; and 
  • it is "just" that the employer should be awarded compensation.

S. 41 sets out the basis on which the award of compensation should be determined.

________________________________________________


The uncertainties inherent in this provision have meant that in the 30 years that have elapsed since its incorporation into UK law, there have been no decisions made in respect of it, although it is thought that there have been a number of out of court settlements. The principal problems with s. 40 have been identified as being the meaning of "outstanding benefit" (which is not defined) and the fact that it was the patent that had to be of outstanding benefit and not the invention protected by the patent. This last difficulty has recently been resolved such that since 2004, compensation is payable if there is outstanding benefit from the patent or the invention (Patents Act 2004).

Kelly and Chiu -v- GE Healthcare Limited

There has now, finally, been a reported decision on s. 40 in the case of Kelly and Chiu -v- GE Healthcare Limited(1). Doctors Kelly and Chiu worked for Amersham International plc (now GE Healthcare Limited) and were the inventors of what proved to be a highly commercially successful radioactive imaging agent that was the subject of a patent granted to Amersham. The product cost in the region of £2.5m to research and develop (a sum recouped in the first year of commercial sales). Total sales of the product to date exceed £1.3bn! Furthermore, the success of this product propelled Amersham International onto the international stage and made the company a takeover target for GE.

During the hearing, the court looked at a number of issues including:

  • the meaning of "inventor" - this is the "actual deviser" of the invention but not somebody who merely contributes to it;
  • under the section prior to its amendment by the Patents Act 2004, the court confirmed that it is the patent (as opposed to the invention) that must be of outstanding benefit to the employer;
  • "outstanding" means something special or out of the ordinary and more than substantial, significant or good. The benefit must be more than one would normally expect to arise from the duties of the employees in question for which they are paid;
  • the patent (or the invention, in the case of those developed following the Patents Act 2004) must have been the cause of the benefit although it does not have to be the only cause. The benefit derived from the patent may have to be apportioned to isolate it from other causes which contribute to the success of the product (such as sales and marketing). The valuation of such benefit is to be performed ex post facto; and
  • under s. 41, the amount of compensation to which the inventor is entitled is that to secure a just and fair award to the employee; such reward should not be limited to an amount that might compensate him for loss or damage (e.g. like assessing damages for breach of contract or tortious behaviour) nor treat the inventor as if he were an external patentee or licensor.

In applying these findings the judge (Mr. Justice Floyd who incidentally was instructed by the writer on an s. 40 issue back in 1986 when a junior barrister) decided that the patent was of outstanding benefit to Amersham because it extended their market monopoly, preventing generic competition, and resulting in, on a very conservative estimate, an additional £50m in revenue.

In looking at the share of this sum which should be due to the inventors, the judge investigated several different analyses including those based on the way universities reward academic inventors as well as the way in which Amersham itself rewarded consultant inventors. On the evidence the judge decided that, with a very conservative view, the inventors were entitled to 3 per cent of the relevant benefit, which he divided between the inventors: 2 per cent (£1m) to Dr Kelly and 1 per cent to the junior inventor, Dr Chiu (£0.5m).

Compensation: conservative but fair

By its nature this is a highly unusual case; the invention was highly successful and made Amersham a world class business. Some might feel that Drs Kelly and Chiu deserved more, but one suspects they were not unhappy at the outcome and the conservative approach of the judge will have given companies engaged in serious R&D some comfort that they will not find themselves on the end of damaging and costly employee claims.
