2 What is the Goal of a Patent Application? To obtain a patent for the client by convincing the Patent Office (i.e., an Examiner) that the invention is patentable It is a form of sales like a proposal Take some pointers from the advertising industry People don t buy when they: Don t feel the need for what you are selling Don t trust the salesman or solution being offered; credibility is lacking. 2

3 Outline Application Drafting Attributes of a well-written application Filing Strategies Legal Requirements Drafting Ideas/Tips Provisional Applications Filing Requirements Strategic Uses/Basis for Priority Pros and Cons 3

4 The well-written patent application What attributes should a well-written patent application have? Describe the invention so one of ordinary skill can understand it Disclose the best mode Provide support for claims of unknown scope Claims narrow enough to avoid prior art Claims broad enough to hamper design around 4

5 The well-written patent application Claims clear enough to provide notice Factually accurate Suitable vehicle for foreign filing Tell a story 5

6 Substantive Legal Requirements 35 U.S.C. 101 Eligible subject matter Utility 35 U.S.C. 112, 1 Enablement Written description Best mode 6

7 Substantive Legal Requirements 35 U.S.C. 112, 2 Definiteness requirement Claims evaluated in light of Content of the application Prior art Interpretation given by those of ordinary skill Special terms Define in the specification/be your own lexicographer 7

8 Substantive Legal Requirements 35 U.S.C. 102 Novel 35 U.S.C. 103 Nonobvious 8

9 Application Drafting Ideas - Tell the Story of Invention Patent application as a vehicle to communicate and persuade The cast of characters The prior art Likely users of the technology Our hero - the inventor(s) 9

10 Application Drafting Ideas - Tell the Story of Invention Setting the stage Background of the invention Unfulfilled needs Failures of others Problems with the prior art Serious nature of the problem 10

11 Application Drafting Ideas - Tell the Story of Invention But what you say may be used against you in a court of law Pitfalls to avoid in the background Disclaimer via criticism and disavowal Written description failure of claimed subject matter to address at least one stated problem or object 11

12 Application Drafting Ideas - Tell the Story of Invention Disclaimer via criticism and disavowal Keep the discussion general, focus on problems and deficiencies of the prior art, not specific features Try a disclaimer: While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, Applicants in no way disclaim these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein. 12

13 Application Drafting Ideas - Tell the Story of Invention Written description failure of claimed subject matter to address at least one state problem or object Revolution Eyewear, Inc. v. Aspex Eyewear, et al., (2009) Avoid listing objects of the invention Try a statement like: The present invention may address one or more of the problems and deficiencies of the prior art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein. 13

14 Application Drafting Ideas - Tell the Story of Invention The hero saves the day Summary of the invention Tie to Background (problem/solution) Broad characterization of benefits (e.g., functional) Recast independent claims Support for the claimed invention Detailed description Refer to advantages of the described features 14

15 Application Drafting Ideas - Define Special Claim Terms Avoid 112, 2 issues Be explicit ( As used herein, the term X means Y ) Claim interpretation Applicant s definition controls Choose your words wisely 15

16 Application Drafting Ideas - Avoid narrow characterizations Overly narrow characterizations of what constitutes the invention have been used to limit the scope of the patented claims (Honeywell Int l. v. ITT Industries, Inc.): "this invention relates to a ", according to the present invention, a ", "a made pursuant to the teachings of the present invention" coupled with a lack of description of alternative embodiments 16

17 Application Drafting Ideas Avoid narrow characterizations Other terms/characterizations to avoid: critical essential key necessary important 17

18 Application Drafting Ideas Avoid narrow characterizations Solutions = Use alternative language such as: "certain embodiments of the present invention include, but are not limited to " Describe as many alternative features and embodiments as possible. 18

19 Application Drafting Ideas - Avoid Dedication to the Public Problem = Disclosed but unclaimed subject matter is dedicated to the public Maxwell v. J. Baker, Inc. Solution = Draft a comprehensive set of claims 19

20 Application Drafting Ideas - Avoid Hyperbole 37 C.F.R Duty of candor and good faith Misrepresentations, misleading statements, and omissions violate this duty. Result = patent at risk for being found unenforceable due to inequitable conduct 20

21 Application Drafting Ideas - Avoid Hyperbole Hoffman-La Roche, Inc. v. Promega Specification contained an example implying that an experiment had been conducted Actually the example was prophetic and never actually performed Result = patent unenforceable due to inequitable conduct Still a problem after Therasense, Inc. v. Becton, Dickinson and Co.? 21

22 Application Drafting Ideas - Disclose Testing Methodologies Honeywell International Claims characterized a polymer yarn by its melt point elevation (MPE). Measured MPE value highly dependent upon technique used to collect the yarn for testing Patentee failed to disclose which technique was used to collect the yarn sample Result = claims insolubly ambiguous and invalid under 35 U.S.C. 112, 2 22

23 Application Drafting Ideas - Think Globally EPO and JPO - problem/solution approach to determine inventive step (obviousness) Telling the story of invention in the application will provide a good basis to meet this requirement EPO - strict interpretation of new matter Limited ability to amend Solution = comprehensive claim set 23

24 Provisional Applications Due to the America Invents Act (AIA), we now live in a first-to-file world More important than ever to secure the earliest possible filing date Increased prominence of provisional applications? Obtaining the earliest possible filing date for each claim "Stacking" provisionals over the course of one year An early filing date does no good if it doesn't stick! 24

25 Provisional Applications 35 U.S.C. 111(b) Act as a placeholder Never substantively examined Automatically lapse or mature one year from the filing date Once filed, applicants can mark patent pending Can not claim priority from another appln. Patent term measured from filing date of subsequent nonprovisional application 25

26 Provisional Applications Filing Requirements A specification A drawing (if required to understand the invention) A cover sheet or cover letter Fee NOT Required A claim An oath or declaration (37 C.F.R. 1.63) An IDS 26

27 Provisional Applications - As a Basis for Priority Domestic Priority 35 U.S.C. 119(e) Foreign Priority (PCT and National Filings) Article 4 of the Paris Convention 27

28 Provisional Applications - Domestic Priority Requirements Nonprovisional application (35 U.S.C. 111(a)) Within 12 months of the filing date of the provisional At least one common inventor Reference to the provisional application Provisional application must satisfy 112, 1 for the invention claimed in the subsequent nonprovisional application 28

29 Provisional Applications - Domestic Priority New Railhead Manufacturing Patent claimed drill bit with certain angle between the bit and its housing Jan 96 Jan 97 Jan 98 Sales spring/ summer 96 2/97 - File Provisional *Sales > 1 Yr.* 11/97 - File Utility 29

30 Provisional Applications - Domestic Priority Court found that the disclosure of the provisional application did not meet the written description requirement with respect to the subsequently claimed drill bit angle Applicant not entitled to priority back to the filing date of the provisional application (limited to 11/97 filing date) Sales occurred more than one year prior to the 11/97 date, thus patent invalid under 35 U.S.C. 102(b) 30

31 Provisional Applications - Foreign Priority Article 4 of the Paris Convention A regular national filing in one country provides a basis for a priority claim in an application filed within 12 months in another member country Governs priority claims in PCT applications Provisional applications are considered a regular national filing Must file PCT/foreign application(s) within 1 year of the filing date of the provisional application. 31

32 Provisional Applications Advantages & Disadvantages Advantage Are relatively simple and inexpensive to file. They do not need a declaration, claims or an IDS. The specification is not examined, and can therefore be informal (PowerPoint presentations, manuals, lab notebook entries, etc.) Disadvantage Must satisfy the requirements of 35 U.S.C. 112, 1 with respect to a later-claimed invention in order to provide any benefit of priority. 32

33 Provisional Applications Advantages & Disadvantages Advantage A utility application can claim priority to multiple provisional applications. Thus, multiple provisional applications can be filed in the one-year time period measured from the earliestfiled provisional application in order to capture changes in rapidly evolving technologies. Disadvantage The various claims of the later-filed utility application may have different priority dates based on multiple provisional application filing dates, which must be evaluated and considered. 33

34 Provisional Applications Advantages & Disadvantages Advantage The patent term of a regular utility patent that claims priority to a provisional application is 21 years from the filing date of the provisional application. They do not have to be in English. Thus, copies of foreign priority documents may be filed as provisional U.S. applications. Disadvantage Examination is delayed up to one year. The content must be evaluated for adequacy of disclosure to support the claim for priority. 34

35 Provisional Applications Advantages & Disadvantages Advantage The filing date of a provisional application can be relied upon to claim the benefit of priority in other countries under Article 4 of the Paris Convention Disadvantage The filing date of a provisional application starts the one-year grace period to complete PCT and/or direct national foreign filings and obtain the benefit of priority. This date must be docketed and kept in mind 35

36 Conclusion Application drafting Patent application as a vehicle to communicate and persuade Substantive and formal legal requirements Tell the story of invention Provisional applications Relatively simple and inexpensive Client pressure to file provisional applications Without quality disclosure loss of priority date and possible loss of patent rights loom 36
