4. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com 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 subsequent amendment of claims –Claims narrow enough to avoid prior art –Claims broad enough to hamper design around The “well-written” patent application 4

5. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com –Claims clear enough to provide notice –Factually accurate –Suitable vehicle for foreign filing –Tell a story The “well-written” patent application 5

6. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Initial Preparation It is important to have a good understanding of the most relevant prior art Don’t want to amend the claims if not necessary 6

7. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Reason not to amend claims case law now emphasizes the negative impact that narrowing amendments have on the scope of a claim –(Festo) 7

8. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Background – Description of Related Art The background enables the Examiner to quickly focus on the importance of the invention Discuss prior art objectively Discuss problems, shortcomings or improvements needed in the prior art carefully Balance reluctance to prematurely characterize the invention against need for advocacy Can be omitted 8

9. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Potential Problems with the “Related Art” Section If the specification indicates that the prior art devices have a certain drawback, and if an accused device similarly has that drawback, a court may find that the accused device does not infringe the patent 9

10. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Summary/Objects Section Acceptable to omit “Objects” entirely Avoid defining an object that might be narrower in scope than the invention Use "objects," "purposes," "features" and "advantages“ carefully The summary should be a mere recitation of the independent claims of the application, almost verbatim 10

11. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Brief Description Of The Drawings Describe as illustrations of embodiments Do not say that the drawings illustrate the “invention” 11

12. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Description Of The Preferred Embodiments Best Mode Requirement –Must disclose the best mode contemplated by the inventor of carrying out the invention 12

Describe how combination of two or more elements achieves new functionality or new synergy. 13

14. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Description Of The Preferred Embodiments Avoid claims that simply list elements or features of invention. Draft claims so that features/elements of invention are related to one another – makes it more difficult for Examiner to argue that improvement is merely predictable use of prior art elements according to their established functions. 14

15. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Description Of The Preferred Embodiments Avoid "The present invention is…” refer to the embodiments of the invention as the preferred embodiments, and not as the invention itself 15

16. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Absolute Terms Be careful about using absolute terms, such as “must”, “critical”, “essential”, “important” to describe features of the invention or other adjectives that might be interpreted as suggesting an element must be part of the invention Courts may construe the claims so as to require such features for infringement, even if the features are not included in the claims 16

17. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Features Not Present In The Invention If the specification makes clear that an invention does not include a particular feature, all devices or methods having that feature may be deemed outside the claims, even though the language of the claims might be broad enough to encompass products or methods with the feature in question 17

18. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Disclosed But Unclaimed Subject Matter Be Careful! Recommended to disclose all readily known equivalents in the specification of an application But, the doctrine of equivalents cannot be utilized to reach disclosed, but unclaimed subject matter 18

19. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com The Use of Functional Language to Define an Element Can create problems if not backed up with solid information/data Functional language alone often does not persuade the Examiner 19

20. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Support for the Claims Ensure that the specification provides clear support for the claims The supporting portions of the specification should be clear and free from ambiguity 20

21. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Claims Provide claims of varying scope Preference should be for structural recitations over functional recitations in device claims A claim should be carefully reviewed to ensure that it does not include any limitations that are not necessary to define the invention and distinguish it from the known prior art 21

22. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Be Clear Make sure your claim element is drafted the way you intended The mere use of the terms “means” or “step” does not automatically invoke 35 U.S.C. § 112, paragraph six The absence of the terms “means” or “step” does not automatically avoid 35 U.S.C. § 112, paragraph six 22

23. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Be Diverse Consider use of parallel sets of claims –one of which is drafted using means (or step) plus function language –the other uses structural language Or –one of which is in method format –the other of which is in device or apparatus format 23

31. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Conclusion Things in a U.S. patent are not always as they may appear to be A claim may be treated as a "means plus function" claim even though it does not use the term "means", or vice versa Language in the specification may be used to limit a claim even though such a specific limitation may not be found in the claim 31

32. California :: Delaware :: Florida :: New Jersey :: New York :: Pennsylvania :: Virginia :: Washington, DC :: www.buchananingersoll.com Conclusion A term in a claim may be given a narrower or different interpretation than would normally be associated with that term A term in a claim may be prohibited from covering an equivalent element under the Doctrine of Equivalents, even if the element is truly equivalent 32
