Tafas vs. Dudas
“Final rule 78 and the hard limit it imposes changes existing lawand deprives applicants of their valuable rights . . . to an unlimited number of continuation and continuation-in-partapplications as a matter of right. “ (emphasis added)
“By so doing, it may also impact applicants’ rights under Sections 102 and 103 and result in the denial of otherwise meritorious patents. For these reasons, the Court finds that Final Rule 78 is a substantive rule.”
Two continuations (Rule 78)

Tafas vs. Dudas
“. . . Limiting RCEs based on application family is a clear departure from the plain language of the statute, which states that the USPTO must provide for the continued examination of each application.”
[35 USC § 132(a) . . . if “the applicant persists in his claim for a patent . . . the application shall be reexamined.”]

Claims with Alternative Language
Ground rules
– Applies to all technologies.
– Permits the USPTO to “restrict“ the alternatives from each other even within a claim
![Page 22: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/22.jpg)
22
Claims with Alternative Language
An “alternative-type” claim is any claim that recites a plurality of alternatively usable members. The rulemaking is not limited to Markush groups.
- Markush group: “selected from the group consisting of plastic, steel and paper”
- Alternative language but not Markush group: “wherein the cup is made of plastic, steel or paper”

23
Claims with Alternative Language
Every claim would be required to be limited to a “single invention.”
Note: A claim that encompasses more than one species, but does not list alternatives, defines one generic invention (but may still be subject to “election of species”).
![Page 24: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/24.jpg)
24
Claims with Alternative Language
When is a claim having alternatives considered to be a single invention?
(1) When all the species encompassed by the claim share a substantial feature essential for a common utility.
or(2) When the alternatives are prima facie obvious over
each other if there is prior art that renders at least one of the alternatives obvious.
![Page 25: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/25.jpg)
25
Claims with Alternative Language
Examples
(A) A series of DNA probes x, x’, x” that share sequence and that all bind the same species of virus.
- the probes have common utility
(B) A series of DNA probes x, y, z, that bind different strains of a single virus, for example, the influenza virus.
- the probes do not have a common utility- the alternatives would be restrictable

Hakim vs. Cannon Avent Group
Hakim originally sued Avent in District Court (W.D. La.) asserting infringement of Hakim’s United States Patents by Avent’s leak-resistant drinking cups.
![Page 29: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/29.jpg)
29
Hakim vs. Cannon Avent Group
The asserted patent was a continuation. In the parent, Hakim distinguished art by stating that the flexible-member opening was a "slit." When the continuation was filed, Hakim notified the examiner that the new claims were broader than those previously allowed. The Examiner allowed the new claims without rejection.
![Page 30: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/30.jpg)
30
Hakim
The District Court (trial court) relied on statements made during prosecution of a parent application to narrowly construe a claim term that was explicitly broadened in the child application. The court ruled that the applicant's efforts to disclaim the perceived estoppel were insufficient.
Federal Circuit affirmed: Although a disclaimer made during prosecution can be rescinded, disclaimed scope, the prosecution history must be sufficiently permitting recapture of the clear to inform the examiner that the previous disclaimer, and the prior art that it was made to avoid, may need to be re-visited.
![Page 31: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/31.jpg)
31
After Hakim –Text to submit with continuing applications
“The claims in the instant application are different than those of the parent application or other related applications.(a) The Applicant therefore rescinds any disclaimer of claim scope made in the parent application or any predecessor application in relation to the instant application. (b) The Examiner is therefore advised that any such previous disclaimer and the cited references that it was made to avoid, may need to be revisited.(c) Further, the Examiner is also reminded that any disclaimer made in the instant application should not be read into or against the parent application.”

32
Practice Point
If you have taken any positions in a parent application that you want to change in a child application, tell your US patent attorney to explicitly disclaim those positions.

KSR
Supreme Court expressed “a need for caution” on granting a patent based on the combination of elements found in the prior art.”The “teaching/suggestion/motivation” rationale is just one that can be used to establish obviousness.
![Page 43: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/43.jpg)

KSR in a nutshell
Where there is (a) A problem(b) And a finite number of identified, predictable
solutions(c) And pursuing this problem leads to “anticipated”
success…(d) Then finding a combination was obvious to try
might show it was obvious under 103.

PTO Obviousness Guidelines
“The mere existence of differences between the prior art and an invention does not establish the invention’s nonobviousness.”Neither motivation nor the problem controls.
![Page 48: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/48.jpg)
48
PTO Guidelines – Rationales
1. Combining prior art elements according to known methods to yield predictable results.2. Simple substitution of one known element for another.3. Use of known technique to improve similar devices/methods/products the same way.4. Applying known technique to known device/method/product ready for improvement to yield predictable results.
![Page 49: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/49.jpg)
49
PTO Guidelines – Rationales
5. Obvious to try – choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success6. Known work in one field of endeavor may prompt variations for use in the same field or a different field due to incentive based on its design or market forces.7. TSM test: A teaching, suggestion or motivation in the prior art would have led the skilled artisan to the invention.
![Page 50: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/50.jpg)
50
What is required from the Examiner?
An “articulated reasoning”
Rejections on obviousness “cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”
![Page 51: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/51.jpg)
51
KSR Drafting Strategies
Caution: Try not to make the “Background” of the invention a KSR roadmap by just stating the problem that the invention solved and that there was a need in the art.
Can you characterize the problem solved as previously unrecognized or unappreciated?

72
Scenario 2A
The inventors have discovered protein PPP and isolated it from I. gotcha membrane preparations. The inventors propose protein PPP is useful to elicit a protective immune response against I. gotcha infections.
![Page 73: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/73.jpg)
73
Scenario 2A
Claim 1: A substantially pure I. gotcha protein, wherein said protein has a molecular weight of about 20 kDa and comprises the amino acid sequence [insert the 10 amino acid sequence], or a homolog, derivative, or immunogenic fragment of said I. gotcha protein.
![Page 74: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/74.jpg)
74
Scenario 2B
Cited art:One art protein (SEQ ID No. 42312) contains the inventors' 10 amino acid sequence, but at an internal site (internal amino acids 5-14). The art’s specification contains generic teachings of how one would isolate any I. gotcha proteins, and generic disclosure of how one would use such a proteins as part of a protective vaccine for I. gotcha. This art is cited for novelty.
The examiner also bases an obviousness rejection on the combination of LOTASEQ's publication and a scientific journal article that describes the use of crude membrane extracts of I. gotcha to elicit antibodies that will cross react with different I. gotcha serotypes.

75
Scenario 2B
Now how would you revise:
Claim 1 (repeated below): A substantially pure I. gotcha protein, wherein said protein has a molecular weight of about 20 kDa and comprises the amino acid sequence [insert the 10 amino acid sequence], or a homolog, derivative, or immunogenic fragment of said I. gotcha protein.

76
Scenario 3: Improvements
(1) The protein vaccine can be provided for oral administration as a solid in food. (2) They have discovered that an equally good vaccine can be made using isolated naked DNA that encodes protein PPP in the vaccine preparation, instead of the protein itself. (3) RNAi can be used, in vitro, to inhibit growth of the bacteria.No additional art has been discovered
![Page 77: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/77.jpg)
77
Scenario 4: More Improvements: Effect of: Publication; 112 Support; Inherency issues
A method of treating and/or preventing infection by I. gotcha, said method comprising inhibiting growth of I. gotcha by contacting said I. gotcha with an antibody or antigen binding portion thereof that binds to an epitope located within amino acids 155-355 of Protein PPP.
(a) Assume Scenarios 2 and 3 have published. (b) Assume Scenarios 2 and 3 have not yet published.
(c) The inventors want to recite both "treat" and "prevent." However, the first application only mentions "prevent" (i.e., the protective vaccine).
![Page 78: SKGF_Presentation_Hot Topics in US Patent Practice-08](https://reader034.vdocuments.net/reader034/viewer/2022052321/556312cbd8b42a811a8b45ae/html5/thumbnails/78.jpg)
78
Scenario 5: More Improvements:More Inherency questions
The inventors have discovered that the incidence of cataracts in patients who have been vaccinated against protein PPP is much lower than the general population.
The inventors propose a method of preventing cataracts by vaccinating a subject with the I. gotcha protein PPP vaccine.
Is inherency a problem?

Scenario 6: The eye receptor
The inventors have used the high homology between DNA encoding protein PPP and that encoding the eye receptor to clone and express the homologous eye receptor.
A new application is filed directed to the new receptor and its expression in animal cells. The specification also has a generaldescription of a series of screening procedures as recited in the claims below. However, there are no working examples in which agonists or antagonists of this receptor are identified.
