Obviousness

1. Obviousness 2012 Donald M. Cameron

2. What’s a patentable invention need to be? • New • Useful • Inventive • Judge made • An 1890 judge-made addition to patentability • 1936: SCC required “a degree of ingenuity” to be present • Now in the Patent Act • “plain as day”, “crystal clear”

3. Hard to express a testfor obviousness/inventiveness What it is • “proper subject matter” – an “invention”, inventive • Obvious, very plain, plain as day, crystal clear The Quantum • an inventive step • a “scintilla” of invention The Path to get it/there • Directly and without difficulty (but lack of difficulty doesn’t mean it’s obvious) • Out of track with what was known at the time The mind it comes from, or doesn’t • Inventive: the product of an inventive mind • Obvious: the product of a non-inventive mind

4. Hugesson J.A. in Beloit – Would any idiot have come up with it, directly and without difficulty? "The test for obviousness is not to ask what competent inventors did or would have done to solve the problem. Inventors are by definition inventive.” "The classical touchstone for obviousness is the technician skilled in the art but having no scintilla of inventiveness or imagination; a paragon of deduction and dexterity, wholly devoid of intuition; a triumph of the left hemisphere over the right. The question to be asked is whether this mythical creature (the man in the Clapham omnibus of patent law) would, in the light of the state of the art and of common general knowledge as at the claimed date of invention, havecome directly and without difficulty to the solution taught by the patent.”

5. Obvious – New Patent Act “28.3 The subject-matter defined by a claim in an application for a patent in Canada must be subject-matter that would not have been obvious on the claim date to a person skilled in the art or science to which it pertains, having regard to (a) information disclosed more than one year before the filing date by the applicant, or by a person who obtained knowledge, directly or indirectly, from the applicant in such a manner that the information became available to the public in Canada or elsewhere; and (b) information disclosed before the claim date by a person not mentioned in paragraph (a) in such a manner that the information became available to the public in Canada or elsewhere.”

6. Beware of formulae: obvious just means obvious • House of Lords in General Tire: • “We agree, however, with what was said by Diplock, L.J. (as he then was) and Willmer, L.J. in the Johns-Manville case [1967] R.P.C. 478 at 493 and 496 deprecating “coining” phrases which may later be suggested to be of general application. “Obvious” is, after all, a much-used word and it does not seem to us that there is any need to go beyond the primary dictionary meaning of “very plain”.”

7. Venn diagrams/Fences: the sunspot analogy

8. The sunspot analogy, cont’d • Key: • Black “umbra”: what’s old • Dark aura “penumbra”: what’s obvious • Yellow: what’s inventive • Outside the picture: what’s not “adjacently possible” (what’s impossible: can’t be done, yet)

9. The “Inventive Step”

10. It’s been done/taught before, in one place Hasn’t been done before but anyone could have done it Can mosiac New Inventive Explaining the difference – How many coins?

11. The Scientific Method & Experiments

12. The Right Approach (according to Sanofi) Windsurfing/Pozzoli

13. Windsurfing case, as updated in Pozzoli (1) (a) Identify the notional “person skilled in the art”; (b) Identify the relevant common general knowledge of that person; (2) Identify the inventive concept of the claim in question or, if that cannot readily be done, construe it; (3) Identify what, if any, differences exist between the matter cited as forming part of the “state of the art” and the inventive concept of the claim or the claim as construed; (4) Viewed without any knowledge of the alleged invention as claimed, do those differences constitute steps which would have been obvious to the person skilled in the art or do they require any degree of invention?

14. Obviousness

15. when experiments drive innovation

16. Plodders get patents too “Very few inventions are unexpected discoveries. Practically all research work is done by looking in directions where the “state of the art” points. On that basis and with hindsight, it could be said in most cases that there was no inventive ingenuity in the new development because everyone would then see how the previous accomplishments pointed the way. The discovery of penicillin was, of course, a major development, a great invention. After that, a number of workers went looking for other antibiotics methodically testing whole families of various microorganisms other than penicillum noatum. This research work was rewarded by the discoveries a number of antibiotics such as chloromycetin obtained from streptomyces venezuelae as mentioned in Laboratoire Pentagone v. Parke, Davis & Co. [1968] R.C.S. 307, tetracycline as mentioned in American Cyanamid Co. v. Berk Pharmaceuticals Ltd. [1976] R.P.C. 231 where Whitford J. said (at p. 257): “A patient searcher is as much entitled to the benefits of a monopoly as someone who hits upon an invention by some lucky chance or inspiration.” Farbwerke Hoechst v. Halocarbon (Ontario) Limited et al(1979), 42 C.P.R. (2d) 145 (S.C.C. per Pigeon J.), at paras. 33-35.

17. Iterative drug design • If this works, tweak it a little and try that • and so on • and so on • and so on

18. So when do experiments result in obvious results? • On the one hand: “It is enough that the person versed in the art would assess the likelihood of success as sufficient to warrant actual trial”. Johns-Manville Corporation’s Patent [1967] RPC 479 (per Lord Diplock) at 495 – the UK “worth a try” test • On the other hand: “Practically all research work is done by looking in directions where the “state of the art” points.” Farbwerke Hoechst

19. Experiments • Two kinds of experiments: • Ones where you already know the answer • Ones where you don’t know the answer

20. Experiments where you already know the answer • It’s been done before • You’ve done it before • good experiments are repeatable • You’ve learned from others • good experiments are repeatable AND • It’s highly likely to happen again • The sun will rise tomorrow • Apples fall from trees

21. Experiments where you already know the answer = confirmatory experiments • Should not be entitled to a patent. • You haven’t really contributed anything new • The solution is obvious.

22. Experiments where you don’t know the answer • If you don’t know, you do research to find out the answer. • Trial and error • If you have errors, you went the wrong way • Therefore the right way wasn’t obvious or you would have done that first • Long recognized to be a legitimate route to a patentable invention • Hoescht: once penicillin discovered, try other microorganisms. That begat chloromycetin and tetracyclin – patentable • American Cyanamid: “a patient searcher is as much entitled to the benefits of a monopoly as someone who hits upon an invention by some lucky chance or inspriation”

23. Experiments where you don’t know the answer • How well can you predict the outcome? • They’ll tend to polarize to either end of the spectrum Guessing…………………….Likely…………….Highly Certain Coin Toss…………Pen at Reception Desk…Sunrise tomorrow

24. Obvious to Try or Worth a Try • Obvious to try • The microorganisms after penicillin discovered • Not determinative: May be obvious, but may not. • Worth a try … but if uncertain of result, it can’t be obvious

25. Experiments when you know an answer’s there • Question: Where are my glasses? • Usual Answer: Look in the obvious places • Where did you last see them? • Where were you last?

26. An expected result • Which is the sharpest knife in the drawer? • One is. • Measure by routine testing • Should the identification of the sharpest knife be patentable? • Probably not – you’re confirming what’s is a given • What if it’s really sharp? Surprisingly sharper than the rest?

27. An expected result • What is it’s melting point? • Merely measuring a physical characteristic • You’re just observing – that’s science • Find me an application and that might be patentable.

28. A bump in the road

29. Would require “undue experimentation” • IKEA furniture • It can be done, but it’s not always easy • To implement an invention after reading a patent, you may have to play around with it a bit • Patent is supposed to be “enabling’ – disclose what you need to know to make it work • If it took “undue experimentation” to implement, the disclosure is lacking • Converse adopted: if there wasn’t undue experimentation to make it, it’s obvious.

30. The easy ones

31. An unexpected result • “Surprise, surprise”

32. Going the wrong way • Doing things backwards resulted in a patented process.

33. Led Directly and Without Difficulty • Reality check: How hard was it for the inventor? • If circuitous, it wasn’t obvious to the inventor • If easy, may or may not be inventive

34. “a mere application of mechanical skill does not make you an inventor” • Corn flakes case: • Q.: Is the first person to do it an inventor? • A.: Not if he was just the technician working the machine. • Over-transmogrified into: If its merely an exercise of mechanical skills, there’s no invention.

35. Other indicia of inventiveness • If it’s “wow” – it’s probably an invention • If creative people say, “I was there and I never thought of it” – it’s probably inventive

36. Summary • If you can put 2 and 2 together and come up with 4, it’s obvious • If you don’t know the answer/solution and have to do research (even if by pedestrian means), it’s not obvious

37. News from the South: KSR

38. KSR – US Supreme Court • Adjustable car pedal for drivers of different heights • Sensor that controlled throttle, etc. • Sensor attached to a fixed pivot point • Prior art: • A+B • A+C • B+C • Invention A+B+C

39. KSR • TSM: • Teaching • Suggestion • Motivation • “a patent claim is only proved obvious if ‘some motivation or suggestion to combine the prior art teachings’ can be found in the prior art, the nature of the problem, or the knowledge of a person having ordinary skill in the art.”

40. KSR • TSM is not a rigid rule – your don’t have to have it in every case in order to find obviousness • Instead, you start with where things were and ask if it was obvious to go to the invention: • “The Court of Appeals considered the issue too narrowly by, in effect, asking whether a pedal designer writing on a blank slate would have chosen …” • “The consequent legal question, then, is whether a pedal designer of ordinary skill starting with Asano would have found it obvious to put the sensor on a fixed pivot point.”

41. KSR – “Predictable results” • “The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” • “… when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” • “If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.”

42. KSR – “Predictable solutions” • “… a court must ask whether the improvement is more than the predictable use of prior art elements according to their established functions.” • “Where there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense.”

43. KSR – some weird stuff • “A person of ordinary skill is also a person of ordinary creativity.” • “And as progress beginning from higher levels of achievement is expected in the normal course, the result of ordinary innovation are not the subject of exclusive rights under the patent law.” • What the heck is “ordinary creativity” or “ordinary innovation”? • OK if: Creating something new but non-inventive?

44. KSR – weird stuff • “The proper question to have asked was whether a pedal designer of ordinary skill, facing the wide range of needs created by developments in the field of endeavor, would have seen a benefit to upgrading Asano with a sensor.” • What triggers the vision? • Surely doesn’t mean you ask the notional person, “Would you see a benefit doing this upgrade? • That’s a leading question inventors are never asked. • OK if: Where were we? Where was obvious to go from there?

45. KSR – weird stuff • Synergy: the whole is greater than the sum of its parts. • THERE’S NO SUCH THING!!!!! • a “patent for a combination which only unites old elements with no change in their respective functions … obviously withdraws what is already known into the fiield of its monopoly and dimishes the resources available to skillful men” • Stuff just does what it does … but you can have a new result – example – the sailboard

46. St. Gobain (2005) Predictability from UK

47. “Worth a try” test gets buried • “Mere possible inclusion of something within a research programme on the basis you will find out more and something might turn up is not enough. If it were otherwise there would be few inventions that were patentable. The only research which would be worthwhile (because of the prospect of protection) would be into areas totally devoid of prospect. The “obvious to try” test really only works where it is more or less self-evident that what is being tested ought to work.” Saint-Gobain PAM SAv.Fusion Provida Ltd., [2005] EWCA Civ 177 at para. 35 (per Lord Jacob).

48. Sanofi

49. If something is worth trying, is it obvious? • UK Johns-Manville 1967 Diplock L.J.: • It’s obvious if it is: • “obvious to try” and • “It is enough that the person versed in the art would assess the likelihood of success as sufficient to warrant actual trial...” • 1972 Technograph case Sach L.J.: • “He would be expected to try out all obvious modifications or combinations of these methods which seemed to him worth trying."

50. 1974 Hoechst F.C.T.D. – obvious if you could predict success • Collier J.: • "Mr. Sim sparred at some length with Dr. Schmutzler, pressing and exploring the hypothesis that the liquid phase process was, to a skilled person, "worth a try". Using the magnifying spectacles of hind-sight (a half borrowed phrase), it is easy to say that any experiment, if time and expense are unlimited … is or was worth a try." • “Using a paraphrase of the “Cripps question”: Was it for all practical purposesobvious to any skilled chemist in the state of chemical knowledge existing at the date of the invention, which consists of the chemical literature available and his general knowledge, particularly in the filed of fluorine chemistry, that he would successfully produce isohalothane (assuming the monomer used here and the hydrogen bromide) in the liquid phase? …
