Damages in One (Fairly) Easy Lesson

1. Damages in One (Fairly) Easy Lesson Patent Law 4.21.08 Prof. Merges

2. Relief Prospective Effect Final injunction issues Issuance Preliminary injunction hearing Complaint filed in District Court Damages assessed for this period if marking (or actual notice)

3. 35 U.S.C. § 284 “[T]he court shall award [the patentee] damages adequate to compensate for the infringement but in no event less than a reasonable royalty for the use made of the invention by the infringer.”

4. 35 U.S.C. § 285 “The court in exceptional cases may award reasonable attorney fees to the prevailing party.”

5. 35 U.S.C. § 287(a) Patentees ... making, offering for sale, or selling ... any patented article ... may give notice to the public that the same is patented, either by fixing thereon the word "patent" or the abbreviation "pat.", together with the number of the patent, or when, from the character of the article, this cannot be done, by fixing to it, or to the package wherein one or more of them is contained, a label containing a like notice. In the event of failure to so mark, no damages shall be recovered by the patentee in any action for infringement, except on proof that the infringer was notified of the infringement and continued to infringe thereafter, in which event damages may be recovered only for infringement occurring after such notice. Filing of an action for infringement shall constitute such notice.

6. Damages • Two measures: • Actual damages: “Lost Profits” • Reasonable royalty • Actual damages & the problem of proof • Panduit Corp. v. Stahlin Bros. Fibre Works, Inc. – P. 1069

7. Compensation principle • “But for” the defendant’s infringing sales, what would the patentee’s profits have been? • NOT a disgorgement remedy: patentee’s loss, NOT infringer’s gain

8. Holding Below • Special Master • 2.5% royalty on all sales by defendant Stahlin during the infringement period • 3/6/62  8/7/70 • Injunction too, of course

9. Panduit’s damage claim • Lost Profits: Stahlin’s sales OR • Reasonable Royalty • Lost Profits on Panduit’s own sales • “Price erosion” profits

10. Patentee Damages Theory • Monopoly price is the inventor’s reward • Competition lowers price; measure “harm from competition”

11. Lost Profits • In 2-firm market, where infringer is second firm, may be easy to calculate • All sales of infringer would have been made by patentee • Always true?

12. Panduit • What does the patentee have to show to prove it would have made sales actually made by infringer?

13. Panduit • What does the patentee have to show to prove it would have made sales actually made by infringer? • “Absence of acceptable noninfringing substitutes”

14. Problem Here • Panduit factor 4, not 2 • Accounting method inadequate

15. “DAMP” test • “Whether lost profits are legally compensable in a particular situation is a question of law that we review de novo.” Poly-Am., L.P. v. GSE Lining Tech., Inc., 383 F.3d 1303, 1311 (Fed.Cir.2004)

16. Ability to manufacture “Normally, if the patentee is not selling a product, by definition there can be no lost profits.” Rite-Hite, 56 F.3d at 1548. The only exception is where the patentee has the ability to manufacture and market a product, but for some legitimate reason does not. Even in these situations, though, “the burden on a patentee who has not begun to manufacture the patented product is commensurately heavy.” Hebert v. Lisle Corp., 99 F.3d 1109, 1120 (Fed.Cir.1996).

17. “[T]he record demonstrates that, despite his later success manufacturing and marketing a product, Wechsler lacked the capability to manufacture his device during the period of infringement.” Wechsler v. Macke Intern. Trade, Inc., 486 F.3d 1286, 1293 (Fed. Cir. 2007)

18. Reasonable royalty: the fallback • Timing • Date infringement began • Hypothetical bargain procedure – pp. 1072-1073

19. Reasonable royalty (cont’d) • Relevance of competitive situation facing firms • Including substitutes • In the background: cross-elasticity of demand

20. Cross-elasticity • How much demand would be lost from the patented product for every dollar increase in its price above the “perfect competition” level?

21. Damages • Two approaches to substitution: • Patentable = unique, therefore, no substitutes. • Antitrust, substitution is a function of cross-elasticity of demand. Therefore, there will usually be substitutes.

22. Elasticity • If price rises by 10% - what happens to demand? • We know demand will fall • By more than 10%? • By less than 10%? • Elasticity measures the extent to which demand will change

23. Elasticity (cont’d) • Price Elasticity of Demand • The responsiveness of demand to changes in price • Where % change in demand is greater than % change in price – elastic • Where % change in demand is less than % change in price - inelastic

24. Elasticity The Formula: % Change in Quantity Demanded ___________________________ PED = % Change in Price If answer is between 0 and -1: the relationship is inelastic If the answer is between -1 and - infinity: the relationship is elastic Note: PED has – sign in front of it; because as price rises demand falls and vice-versa (inverse relationship between price and demand)

25. Elasticity in this example • - 29% / 66% = - .43 • NB: If the decision had been to raise the price, the firm would have lost revenue (so “inelastic demand” can still mean net loss in revenue due to price rise)

26. Elasticity • Cross Elasticity: • The responsiveness of demand of one good to changes in the price of a related good – either a substitute or a complement % Δ Q of good x __________________ XED = % Δ Price of good y

27. Cross elasticity - example • Increase price of good Y from $1.00 to $1.10 • Demand for good X increases from 100 to 120. • Cross-elasticity: 20%/10% = + 2.

28. Elasticity • Goods which are complements: • Cross Elasticity will have negative sign (inverse relationship between the two) • Hot dogs and mustard • Goods which are substitutes: • Cross Elasticity will have a positive sign (positive relationship between the two) : e.g., public transit and car sales • These are the ones we are usually interested in in patent cases

29. Cross-elasticity and substitutes • Number and closeness of substitutes – the greater the number of substitutes the more elastic the demand for a given product will be

30. The Fallback – Reasonable Royalties • “Hypothetical Bargain” principle • When? – Date infringement began • Factors • Do not reward infringement !! • Available noninfringing substitutes? • Does infringer get a profit?

33. Principle/Goal of Patent Damages Doctrine Goal: find "the difference between [patentee’s] pecuniary condition after the infringement, and what his condition would have been if the infringement had not occurred." Yale Lock Mfg. Co. v. Sargent, 117 U.S. 536, 552.

34. Goals/Principles II The question to be asked in determining damages is "how much had the Patent Holder and Licensee suffered by the infringement. And that question [is] primarily: had the Infringer not infringed, what would Patent Holder-Licensee have made?" Livesay Window Co. v. Livesay Industries, Inc., 51 F. 2d at 471.

35. Numerous cases approach this from the patentee’s perspective • How much would the patentee have been able to charge in the absence of infringement? • How many units would it have sold?

36. Growing Sophistication • Crystal Semiconductor Corp. v. Tritech Microelectronics Int'l, Inc., 246 F3rd 1336, 1356 (FC 2001) • "[T]o determine a patentee's market share, the record must accurately identify the market. This requires an analysis which excludes alternatives to the patented product with disparately different prices or significantly different characteristics."

37. Grain Processing Corp. v. Am. Maize Products • Major step in development of balanced counterfactual infringement analysis • How would infringer respond to presence of valid patent in the market space?

38. History matters! • Following trial on damages, the District Court, Easterbrook, Circuit Judge, sitting by designation, awarded patent holder reasonable royalty, 893 F.Supp. 1386, and holder appealed. The Court of Appeals, 108 F.3d 1392, remanded for reconsideration of lost profits issue. On remand, the District Court, Easterbrook, Circuit Judge, 979 F.Supp. 1233, again held that holder was not entitled to lost profit damages and awarded royalty instead.

39. Grain Processing When basing alleged lost profits on lost sales, patent owner has an initial burden to show a reasonable probability that he would have made the asserted sales but for the infringement; once the patent owner establishes a reasonable probability of "but for" causation, the burden then shifts to the accused infringer to show that the patent owner's "but for" causation claim is unreasonable for some or all of the lost sales.

40. Key holding Fact that competitor's product, as made by alternative, noninfringing process, was not sold on the market during period that patent was infringed by product as it was made by infringing processes did not render product as made by noninfringing process unavailable, for purpose of patent holder's claim for lost profits.

41. Easterbrook: 979 F.Supp. 1233, 1236 • “A product that is within a firm's existing production abilities but not on the market--in this case, Lo-Dex 10 made by Process IV (see 893 F.Supp. at 1389-90)--effectively constrains the patent holder's profits. Potential competition can be as powerful as actual competition in constraining price. William J. Baumol, John C. Panzar & Robert D. Willig, Contestable Markets and the Theory of Industry Structure (1982).”

42. Grain Processing • 4 production processes; one (# 4) non-infringing • “Practically instantaneous” transition from infringing process to noninfringing one • See why this is important? • Process 4 was not actually used . . .But it easily could have been!

43. Lesson: • “There is nothing quite so useful as a good theory.” • !!

44. Note dictum, at p. • Patentees have “significant latitude to prove and recover lost profits for a wide variety of foreseeable economic effects of the infringement.”

45. Examples • Rite Hite v. Kelly, 56 F.3d 1538, 1550 (Fed.Cir.1998). • Infringer’s sale of “generation 1.0” model took sales away from patentee’s “generation 2.0” product; lost profits damages awarded even though patentee no longer selling generation 1.0 product

46. Examples • American Seating Co. v. USSC Group, Inc.514 F.3d 1262, 1270 (Fed. Cir. 2008) “Although the evidence in this case was relatively sparse, it sufficed for the jury to assume that USSC offered the VPRo I for sale and then substituted the non-infringing VPRo II -- a bait-and-switch -- and to find that absent USSC's offer to sell the VPRo I, the sales would have gone to American Seating.”

47. Other damage theories Relative market share of patentee relative to non-infringers would remain the same without the infringer. • Price erosion • Market share rule • Lost sales of related but unpatented products • Post-expiration sales

48. Other damage theories • Price erosion • Market share rule • Lost sales of related but unpatented products • Post-expiration sales Components and other related products which are normally sold with the patented product.

49. Other damage theories Head-start theory. Competitor cannot enter market immediately post-expiration. • Price erosion • Market share rule • Lost sales of related but unpatented products • Post-expiration sales

50. Other damage theories Relative market share of patentee relative to non-infringers would remain the same without the infringer. • Price erosion • Market share rule • Lost sales of related but unpatented products • Post-expiration sales
