Lamson v. United States
117 Fed. Cl. 755
Fed. Cl.2014Background
- Dr. Ralph J. Lamson owns U.S. Patent No. 6,425,764, claiming methods that use interactive virtual reality to evaluate or treat a psychological, psychiatric, or medical condition in a human patient (claims 1, 19, 23, 26).
- Lamson sued the United States under 28 U.S.C. § 1498(a) alleging unauthorized use of the patented VR therapy by DOD, VA, and government-funded contractors (including programs to habituate/desensitize soldiers). Count 2 (takings) was previously dismissed; Count 1 (§ 1498 claim) remained.
- The government moved for summary judgment, invoking 35 U.S.C. § 287(c) (medical-immunity provision) as a complete defense for medical uses performed by or under direction of licensed practitioners at government medical facilities.
- Lamson conceded the facts would fit § 287(c)’s factual predicate but argued § 287(c) is a Title 35 limitation that cannot be asserted against the United States in a § 1498(a) suit because § 1498 creates a separate remedial scheme. He also argued some VR uses (e.g., habituation) are preventive medical treatment covered by the patent.
- The court treated the factual allegations as true for the motion, resolved only legal questions, and granted summary judgment for the government.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether § 287(c) (medical immunity) is available to the U.S. as a defense in a § 1498(a) suit | Lamson: § 287(c) is a Title 35 remedial rule that was not expressly incorporated into § 1498, so the U.S. cannot invoke it in § 1498(a) actions | U.S.: Motorola and the Revisor’s Note make all defenses available to the U.S. in § 1498 suits; § 287(c) is an immunity/defense, not a damages limitation, so it applies | Court: § 287(c) is a defense (an immunity) and is available to the U.S. in § 1498(a) suits; claims covered by § 287(c) are barred |
| Whether § 287(c) is a damages-limiting provision like §§ 287(a)–(b) (thus inapplicable under Motorola) | Lamson: § 287(c) is codified in Title 35 and should not be read into § 1498 absent express incorporation | U.S.: § 287(c) is a substantive immunity (complete bar) distinct from notice/marking limits in §§ 287(a)–(b) | Court: § 287(c) is an immunity (complete defense), not merely a damages limitation, and so differs from the Motorola context; available to U.S. |
| Whether uses of VRIT to habituate/desensitize soldiers (combat simulators) fall within the patent scope | Lamson: such habituation is preventive medical treatment that fits the patent’s treatment/evaluation claims | U.S.: the ’764 patent claims require treatment/evaluation of a human patient with a medical/psych condition; non-patient or non-treatment uses lie outside the claims | Court: The patent’s method claims require application to human patients with medical/psych conditions; non-treatment uses (e.g., general combat-simulator habituation) are outside the patent and do not give rise to § 1498 liability |
| Remedy/disposition | Lamson: (sought compensation under § 1498) | U.S.: summary judgment dismissal based on § 287(c) and lack of patent scope for non-treatment uses | Court: Granted summary judgment for government; dismissed claims; each party bears own costs |
