Failed PTAB Bill Reemerges For a 6th Time

Yesterday, U.S. Senators Chris Coons (D-Del.),Thom Tillis(R-N.C.), Dick Durbin (D-Ill.), and Mazie Hirono (D-Hawaii) introduced the Promoting and Respecting Economically Vital American Innovation Leadership (PREVAIL) Act (here). Also yesterday, some of the very same senators introduced the Patent Eligibility Restoration Act of 2023. 

The co-introduction of these bills suggests a plan to drive compromise on patent eligibility.…

Tepid Demand for New Proceeding

Supplemental Examination (SE) is a new mechanism of the AIA designed to effectively cure inequitable conduct via a new post grant proceeding of the USPTO. The new mechanism went into effect on September 16, 2012 along with the other major post grant provisions.

As reported by Patently-O last week, only a handfulof SE filings have been submitted to date, far fewer than expected by some.

In operation, SE allows a Patentee to submit very detailed explanations of potential issues that may render the patent invalid under an inequitable conduct theory. Upon submission of Substantial New Questions of Patentability (SNQs) detailing such potential defects, the Office will reconsider the information; that is to say the Office will perform a “supplemental examination.” Once such issues are considered and dispatched by an SE certificate, the subject patent would be free of inequitable conduct charges based on the issues considered in the SE. On the other hand, should the materials presented raise an SNQ, a form of patent reexamination is conducted (differing from typical practices in that it is not be limited to patents and printed publications).

Sounds like a great idea….and it was, prior to Therasense.…

Enactment of America Invents Act to Change Inter Partes Patent Reexamination Practice Immediately

The USPTO is currently hard at work preparing to implement and adapt agency practices to comport with the various provisions of the Leahy-Smith America Invents Act. As many features of the legislation will require a significant USPTO rule making effort, most of the provisions of the Act will not become effective until the 1 year anniversary of enactment. In this regard, the USPTO has reportedly penciled in September 20th as the target date for the expected enactment of the Leahy-Smith America Invents Act.

While most provisions of the Act will not take effect until a year after enactment, there are some very important changes to patent reexamination practice that will become effective immediately…..likely, in a few weeks time.…

NTP Decision Explains Propriety of 112 Analysis in Patent Reexamination

MPEP §§ 2258 and 2658 explain that, during a reexamination proceeding, the USPTO will not analyze originally issued claim language with respect to 35 U.S.C. § 112, 1st paragraph. (It will, however, consider such issues where new claim language is introduced by amendment).

On the other hand, 35 U.S.C. § 112, 1st paragraph is considered where the patent subject to reexamination has claimed the benefit of the filing date of an earlier filed U.S. or foreign patent application.  MPEP § 2258 (I)(C). That is to say, if the parent patent does not support the claims of the child patent claims under reexamination, a substantial new question of patentability (SNQ) may be presented that is based on intervening patents or printed publications as the child patent claims under reexamination would not be entitled to the filing date of the parent. In such a case, the practical effect is that the original patent claims are analyzed under 35 U.S.C. § 112 relative to the priority application.

The challenge to the priority determination is in practice a  “back door” attack on the original patent claims’ compliance with 35 U.S.C. § 112, 1st paragraph, especially where the patent subject to reexamination is a “straight continuation” having an identical disclosure to its parent.

In last week’s NTP decisions, this strategy was blessed by the CAFC.

SNQ Review Options Vary Significantly Between Ex Parte & Inter Partes Patent ReexaminationAs discussed back in March relative to inter partes reexamination, the proper mechanism for seeking review of a denied Substantial New Question Of Patentability (SNQ) may depend on the status of the claims of the proceeding. For example, where inter partes reexamination is denied as to certain claims of a request, the appeal of such SNQ denial is improper. Yet, if all claims are actively reexamined, denied SNQs may be appealed to the BPAI. Patent Owners may petition the finding of an SNQ in very limited circumstances. (i.e., an ultra vires Order) In ex parte patent reexamination, Patent Owners are now expected to appeal the finding of an SNQ based upon the June 25, 2010 Federal Regsiter Notice. Denied SNQs are only petitionable by third parties if reexamination is denied as to all requested claims.Keeping the various options straight in your head can be a challenge. Below is a graphic that lays out the options for easy reference.

Petition or Appeal?–Pursuit of SNQ Denial at the USPTOWhen pursuing inter partes patent reexamination, denial of a Substantial New Question of Patentability (SNQ) by the USPTO can be especially troubling to third party requesters. This is because a third party is estopped from asserting in litigation the “invalidity of any claim finally determined to be valid and patentable on any ground which the third-party requester raised or could have raised during the inter partes reexamination proceedings.” 35 U.S.C. § 315(c).Denied SNQs raise the fear of potential district court estoppel relative to the prior art underlying the denied SNQ. For this reason, third parties will almost always dispute such denials internal to the USPTO–even where the claims of the patent remain rejected based upon other SNQs of the same request.But, what is the appropriate vehicle for such a dispute, petition or appeal? The answer to this question will depend upon whether or not the denied SNQ pertains to a claim that is being actively reexamined on other grounds. As explained by an expanded panel of the Board of Patent Appeals & Interferences (BPAI) yesterday in Belkin International et al., v. Optimumpath LLC, the denial of an SNQ in inter partes patent reexamination is  petitionable, not appealable. In Belkin U.S. Patent 7,035,281 was reexamined (95/001,089). The request was granted as to claims 1-3 and 8-10, but denied as to claims 4-7 and 11-31.The denial of the SNQs applied to claims 4-7 and 11-31 was petitioned to the Director of the Central Reexamination Unit. Upon reconsideration, the Director refused to reverse the examiner. During prosecution, the rejection of claims 1-3 and 8-10 was later withdrawn by the examiner. Thereafter, the third party appealed the withdrawn rejection and the denial of the SNQs. On appeal, the BPAI affirmed the examiner’s decision to withdraw the rejection and confirm the patentability of claims 1-3 and 8-10. As to the appeal of the denied SNQs, the BPAI explained that such issues may not be appealed to the Board. . . . 35 U.S.C. § 312 states that the Director makes such determinations (of whether a substantial new question of patentability exists) and that the determination “by the Director . . . shall be final and non-appealable.” Only when the Director makes the determination that a substantial new question of patentabilityaffecting a claim of a patent is raised (i.e., that a substantial new question of patentability exists for a particular claim) shall an inter partes reexamination of the claim(s) in question be performed for resolution of the question (35 U.S.C. § 313). Therefore, on the other hand, when the Director makes a determination that a substantial new question of patentability affecting a particular claim is not raised, the Director does not order inter partes reexamination of the patent with respect to those claims. Under those circumstances, no reexamination is performed with respect to those proposed substantial new questions of patentability. Also, as pointed out above, the Director’s determination that no substantial new question of patentability was established for any particular claim(s) is final and non-appealable (35 U.S.C. § 312(c)).Since, under 35 U.S.C. § 312 and 35 U.S.C. § 313, reexamination of the patent claims in question cannot proceed when the Director makes a determination that a substantial new question of patentability has not been raised for those claims and that the Director’s determination is non-appealable, no final decision, whether favorable or unfavorable, can be rendered pertaining to those claims. Under 35 U.S.C. § 315(b), a third-party requester may appeal with respect to any “final decision favorable to the patentability” of disputed claims. However, as described above, if the Director makes the non-appealable determination that no substantial new question of patentability has been raised, then reexamination is not performed for those claims in question with respect to the corresponding prior art references. There cannot have been a final decision (either favorable or unfavorable) on the patentability of the claims in question under 35 U.S.C. § 315(b), the claims not having been reexamined in the first place for lack of a substantial new question of patentability. (emphasis added)The decision continues on to explain that the denial of SNQs is propoerly pursued by petition to the Director (which Belkin filed to no avail; 37 C.F.R. § 1.927). Note that had an SNQ been found but the corresponding rejections not adopted, appeal of non-adopted rejections would have been appropriate.Of course, a patent owner’s seeking to reverse an accepted SNQ in ex parte patent reexamination may pursue the matter to the BPAI

When pursuing inter partes patent reexamination, denial of a Substantial New Question of Patentability (SNQ) by the USPTO can be especially troubling to third party requesters.

Deja Vu All Over Again in Patent Reexamination?A prejudice common to Patent Owners is that patent reexamination serves to re-hash previously distinguished prior art for harassment purposes. While this is certainly not the case, the difference between a previously considered issue and a “Substantial New Question of Patentability” (SNQ) need not be very pronounced.Since In re Swanson, the standard for establishing a (SNQ) in a patent reexamination has been quite liberal. A requester need only establish that the submitted art be presented in a new light. Thus, previously considered prior art can be re-considered, if applied to the claims in a slightly different manner than that of the original prosecution.However, that is not to say that every proposed SNQ is…well, an SNQ.In such instances, when is the best time to object, and what is the proper procedural mechanism, petition or appeal? A recent decision of the BPAI has helped clarify these issues for ex parte patent reexamination.Last June, I explained the case of Ex parte Yasukochi et al, which pertained to an owner initiated ex parte patent reexamination. At issue in Yasukochi is U.S. Patent 7,034,083 (“‘083 Patent”) of Hisamitsu Pharmaceutical.  After the ex parte patent reexamination was initiated by Hisamitsu on certain prior art, the examiner introduced a rejection based upon a reference (Tsubota) previously applied in the original prosecution. The Patentee argued that this reference was being applied in the exact same manner as the original prosecution, and, as such, could not constitute an SNQ. On appeal, the BPAI refused to consider the issue, taking the position that the propriety of an SNQ is a question of procedure to be addressed by petition. Under the BPAI’s reasoning, the patent owner should have filed a petition under 37 CFR § 1.181 to the Director of the CRU when the examiner initially raised the new rejection.  Of course, such a petition was untimely at the time of the appeal. (since more than two months have elapsed since the rejection was made).The decision seemed to be at odds with In re Recreative Technologies Corp., 83 F.3d 1394, 38 USPQ2d 1776 (Fed. Cir. 1996) as well as  In re Portola Packaging Inc., 110 F.3d 786, 42 USPQ2d 1295 (Fed. Cir. 1997), which both considered the question of an appropriate SNQ in patent reexamination at the Board level (and beyond).A week thereafter, the USPTO determined that issues relating to an SNQ determination, while still considered a procedural question, are to be delegated the BPAI for a final determination. In the June 25, 2010 Federal Register Notice, the Office has clarified that assuming an SNQ is contested prior to appeal, either by petition or Patentee response, that the BPAI will now finally decide the issue. Likewise, for reexaminations pending prior to 6/25/10, if the issue was not raised prior to appeal, the Patentee may still raise the issue with the BPAI.So, in essence, Hisamitsu was afforded a chance to pursue the issue before the BPAI on rehearing.On further consideration, the BPAI found that the change in procedure was not applicable to rejections applied during patent reexamination. The Board reasoned that the proper avenue for such a review was still by way of petition, stating:We hold that the Notice does not delegate authority to the Board to decide whether a particular rejection made during the course of prosecution following a properly initiated reexamination is outside the scope permitted in an ex parte reexamination. The notice addresses those situations where a patent owner challenges an examiner’s threshold determinationthat a substantial new question has been presented. The Notice delegates the authority “to review issues related to the examiner’s determination that a reference raises a SNQ” to the Chief APJ. Notice, 75 Fed. Reg. 36,357. The examiner’s determination is not challenged in this appeal. Appellant requested that its patent be reexamined. Request for Ex parte Reexamination, filed March 22, 2007, pp. 1-6. The examiner held that a substantial new question had been raised by that request. Order Granting Request for Ex Parte Reexamination dated April 11, 2007, pp. 3-5. The examiner’s determination that the cited references raise a SNQ is unchallenged. (emphasis added)The Board seemed to emphasize throughout the rehearing opinion (here) that the Patentee had presented the initial SNQs necessary to initiate the reexamination. As to the Tsubota rejection, the examiner made clear in the rejection that the reference was previously considered. The examiner explained that previously submitted declaration evidence was ineffective against the reference as failing to account for certain claim language, hence the SNQ. Thus, even had Hisamitsu petitioned, the PTO seemed to have a legitimate ground for the re-presentation of the Tsubota reference. Interestingly, it appears the examiner searched for prior art during patent reexamination. Several references used in rejecting the claims were neither submitted by the patentee or of record in the earlier application prosecution; this is quite unusual.All is not lost for Hisamitsu, during the patent reexamination a broadening patent reissue was filed that remains suspended. Absent appeal to the CAFC, the reissue proceeding can now proceed. Perhaps Hisiamitsu will have more luck in this post grant proceeding. (12/108,934) 

A prejudice common to Patent Owners is that patent reexamination serves to re-hash previously distinguished prior art for harassment purposes.

Expanded BPAI Panel Shoots Down Repackaged SNQSince In re Swanson, the standard for establishing a Substantial New Question of Patentability (SNQ) in a patent reexamination has been quite liberal. A requester need only establish that the submitted art be presented in a new light. Thus, previously considered prior art can be re-used, if applied to the claims in a slightly different manner than that of the original prosecution. Understandably, since Swanson, arguing that a rejection adopted by the Office in patent reexamination does not in fact present the previously considered art in a new light has been an uphill battle.Yesterday, the USPTO found a rare SNQ it didn’t like….and pigs were seen flying down Dulany Street.U.S. Patent 6,780,079 is the subject of litigation styled MuzzyProducts Corporation v. Primos Inc., U.S. District Court of Georgia 4:05cv182. This case was stayed in 2007 pending the outcome of the reexamination, 90/008,081. The ‘079 Patent relates to a devices used in hunting for attracting game (game calling).Original ProsecutionDuring the original examination of the ‘868 application which eventually issued as the ‘079 patent, the claims were rejected under 35 U.S.C. § 103(a) as obvious over prior art Patent No. 5,607,091 “Musacchia”. The Examiner stated that while Musacchia does not disclose a hunting device for producing sounds that has a unitary construction, “unitary construction of the hunting device would have been obvious to one of ordinary skill in the art, since this would aid in the portability and usage of the device.”In response, the inventor, Mr. John Musacchia Jr., (prior art invented by his father) filed a Declaration seeking to establish non-obviousness through long-felt need.After extensive prosecution, the original Examiner maintained the rejection of the claims over Musacchia stating that “Musacchia discloses the claimed invention except for the game call device constructed as one piece” and that “[i]t would have been obvious to one having ordinary skill in the art at the time the invention was made to form the game call device as one piece, since it has been held that forming in one piece an article which has formerly been formed in two pieces and put together involves only routine skill in the art. Howard v. Detroit Stove Works, 150 U.S. 164 (1893).”After further prosecution, the Applicant appealed to the Board. The original Board panel reversed the original Examiner’s rejection stating that there is no per se rule that “forming several pieces integrally as a one-piece structure would have been obvious . . . [,]” and “in this case, one must determine if it would have been obvious to one of ordinary skill in the art at the time the invention was made to make Musacchia’s separate call and platform as a one-piece structure.” Subsequently, the application was then allowed by the examiner.Request for ReexaminationIn the request for reexamination, the Requester argued that the Declaration filed during the prosecution of the ‘079 patent was only considered as to whether it demonstrated long-felt need, and not considered by either the original Examiner or the original Board panel as including admissions.The USPTO adopted this reasoning explaining the admissions to be statements made by the Patent Owner in his declaration and remarks that identify the long-unfelt need. Specifically, these remarks explain that a one piece design was considered desirable by those of skill in the art and would predictably result in preventing the loss of game calls, maintaining a true sound, and reducing the cost of the game call.In this regard, the Office stated that, when considered as admissions, the statements of the Declarationprovide evidence of obviousness, which was specifically pointed out as missing in the prior examination, and therefore, cast Musacchia ‘091 in a new light. The teachings of Musacchia ‘091 considered in conjunction with the admissions are a new question of patentability not previously considered. As such, the teachings of Musacchia ‘091, in conjunction with the admissions in the record, raise a substantial new question of patentability.Board DecisionThe Board remanded (decision here) the reexamination back to the Central Reexamination Unit for termination explaining that:While the CRU Examiner may be correct in asserting that the original Examiner and the previous Board panel considered the statements in the Declaration only in the context of long-felt need, these statements do not alter the purpose for which the CRU Examiner now relies on the Musacchia reference for finding the existence of a SNQ. In particular, the CRU Examiner does not apply the statements in the Declaration to gain any new understanding as to the teachings of the Musacchia reference, but rather, uses the statements merely to reach a different legal conclusion as to obviousness. While the CRU Examiner asserts that the statements in the Declaration casts Musacchia in a “new light,” the CRU Examiner’s position suggests that the CRU Examiner is viewing the Declaration, not the Musacchia reference, in a new light.PPG Comment : The Requester gets an “A” for effort.Essentially, this reexamination was pursued to leverage the perceived change in obviousness standards caused KSR International Co. v. Teleflex Inc (‘079 Patent issued pre-KSR). Ths request was submitted under the guise of declaration admissions in the hopes that applying KSR to the same art would yield different results. Of course, MPEP 2216 makes it very clear that KSR does not impact the SNQ analysis.**Fortunately for the patent owner, as of June 25, 2010, the Board may now properly review the examiner’s determination that a SNQ exists. Prior to June 25, 2010 the Patent Owner’s argument would have been rejected by the BPAI as a petitionable issue.

Since In re Swanson, the standard for establishing a Substantial New Question of Patentability (SNQ) in a patent reexamination has been quite liberal. A requester need only establish that the submitted art be presented in a new light. Thus, previously considered prior art can be re-used, if applied to the claims in a slightly different manner than that of the original prosecution.

bigq copyg class=”alignleft size-full wp-image-1265″ title=”bigq copy” src=”https://www.patentspostgrant.com/wp-content/uploads/2010/02/bigq-copy.bmp” alt=”bigq copy” width=”218″ height=”176″ />What Exactly is a Substantial New Question of Patentability Anyway?

As noted in Part I of this two part series, the purpose of a request for patent reexamination is quite simple, to present SNQs relative to some or all of the claims of an issued patent.  Certainly there are numerous grounds to challenge a patent in a Federal District Court.  However, one must realize that an SNQ is a particular subset of the universe of available grounds applied at the USPTO.  The appropriate subset is explicitly identified by the reexamination statutes.  Simply stated, proper SNQs must be based on patents and/or printed publications only.  So, a proper SNQ cannot embrace arguments relating to public use/on sale bar, inequitable conduct, 35 U.S.C §112, or statutory subject matter, for example.

For “a substantial new question of patentability” to be present, it is only necessary that: (A) the prior art patents and/or printed publications raise a substantial new question of patentability regarding at least one claim, i.e., the teaching of the (prior art) patents and printed publications is such that a reasonable examiner would consider the teaching to be important in deciding whether or not the claim is patentable; and (B) the same question of patentability as to the claim has not been decided by the Office in a previous examination or pending reexamination of the patent or in a final holding of invalidity by the Federal Courts in a decision on the merits involving the claim. It is not necessary that a “prima facie” case of unpatentability exist as to the claim in order for “a substantial new question of patentability” to be present as to the claim. Thus, “a substantial new question of patentability” as to a patent claim could be present even if the examiner would not necessarily reject the claim as either fully anticipated by, or rendered obvious in view of, the prior art patents or printed publications. MPEP 2240/2640

In our last discussion, in addition to the above distinctions, we identified common misconceptions and practitioner errors in preparing reexamination requests.  Yet, assuming you have omitted such materials, and have a proper basis for your SNQ, what are some best practices in presenting SNQs to the Office?
Continue Reading Effectively Presenting a Request for Patent Reexamination(Part II of II)

It is well established that patent reexamination is limited in scope, by statutory definition, to unpatentability issues presented by patents and printed publications.  In other words, invalidity and/or unenforceability issues relating to inequitable conduct, public use or sale[1], subject matter eligibility, enablement and best mode are generally[2] outside the scope of patent reexamination (See 37 C.F.R. §§1.552 & 1.906).  Yet, a little known exception to these bright line rules exists with respect to previously submitted declaration evidence; an exception that has recently been narrowed even further. 

MPEP 2258.01, in its current form, describes the right of a third party to attack the sufficiency of original prosecution declaration evidence as a basis for a reexamination request…
