MEMORANDUM OPINION
In the 1990’s, Congress twice significantly altered the patent law landscape. First, in 1994, Congress enacted the Uruguay Round Agreements Act,
Presented here is the following, as yet unresolved, question concerning the application of AIPA’s PTA provision:
Whether 35 § 154(b)(1)(B) requires that an applicant’s PTA be reduced by the time attributable to an RCE, where, as here, the RCE is filed after the expiration of AIPA’s guaranteed three year period.
For the reasons that follow, § 154’s plain language neither addresses nor requires that an applicant’s PTA be reduced by the time required to process an RCE that is filed after the expiration of the three year period.
I.
Exelixis, Inc. (“Exelixis”), a Delaware corporation with its principal place of business in San Francisco, California, is the owner , of United States Patent No. 7,989,-622 (“the '622 patent”). This patent— entitled “Phosphatidylinositol 3-Kinase Inhibitors and Methods of their Use” — cov
The administrative record reflects the various events that occurred in the course of the prosecution and examination of the application that led to the issuance of the patent. Only a few of these events — those pertinent to the PTA calculation and hence to the question presented — merit mention here.
First, the record reflects that the application for the '622 patent
The next event with PTA significance occurred, as the record reflects, on March 9, 2011, approximately 38 months after the application filing date, when the PTO issued a Final Rejection of the application. Barely a month later, Exelixis, on April 11, 2011, filed the RCE at issue here. This RCE modified and supplemented the application as follows: (i) claims 1-12, 14, 15, and 17-33 were cancelled, (ii) claims 13 and 16 were amended, (iii) claims 34-38 were added, and (iv) additional support was provided for the amended and added claims.
Thereafter, the PTO, with commendable, if, -with respect to this application, uncharacteristic alacrity, responded less than three weeks later by mailing to Exelixis a “Notice of Allowance & Fees Due” with respect to the application. This Notice advised Exelixis (i) that “prosecution on the merits has closed,” (ii) that the application “is allowed for issuance as a patent,” and (iii) that the PTA for the '622 patent was calculated as 283 days, meaning that the '622 patent term would extend 20 years plus 283 days from the date of the patent application.
The record next shows that on April 28, 2011, Exelixis paid the issue fee, but then for reasons not disclosed in the record, the PTO did not mail the “Issue Notification” to Exelixis until July 17, 2011. The '622 patent issued thereafter on August 2, 2011. The Issue Notification included the PTO’s final PTA calculation for the patent,
Exelixis does not dispute the PTO’s calculation of A delay, C delay, or C reduction; instead, the parties’ dispute focuses sharply on the PTO’s B delay calculation. The PTO contends that the 85 days of B delay is arrived at by subtracting the number of days attributable to the RCE, 114 days (April 11, 2011 to August 2, 2011), from 199 days (the number of days from the expiration of the three year period— January 15, 2008 to January 15, 2011 — to the issuance of the patent on August 2, 2011). Exelixis disagrees with the PTO’s decision to reduce the PTA by the RCE and argues instead that the proper B delay calculation is 199 days, the number of days between the end of the § 154(b)(1)(B) guaranteed three year period (January 15, 2011) and the issuance of the patent (August 2, 2011). The following time line illustrates the '622 patent’s path to issuance and the parties’ competing B delay calculations:

As the timeline shows, the PTO’s notice of rejection, Exelixis’ RCE, the PTO’s notice of allowance, and the issuance of the patent all occurred after the expiration of the three year period that commenced on the application filing date. And as the timeline also makes clear, the question that divides the parties on these facts is whether § 154(b)(1)(B) requires that, or even addresses whether, any PTA be reduced by time attributable to an RCE where, as here, the RCE is filed after the expiration of the three year guarantee period specified in that statute.
II.
Resolution of this question is informed by a brief overview of AIPA’s PTA provisions. The starting point in this overview is to note that Congress, in 1994, in order to implement international agreements, amended the patent laws to extend the length of a patent term to 20 years, measured from the date of the patent application.
A. The Patent Application Process
In order to patent an invention, a person must apply to the PTO for a patent. 35 U.S.C. § 111. A PTO patent examiner then determines whether the “applicant is entitled to a patent under the law,” and, if so, the PTO issues a patent. 35 U.S.C. § 131. If the patent examiner makes a contrary finding, then the PTO will issue a notice of rejection that puts forth “the reasons for such rejection.” 35 U.S.C. § 132(a). If the applicant receives a rejection notice, the applicant may continue to pursue the issuance of the patent as is, or may make an amendment to the patent application. On the second, or any subsequent, examination of the patent application, the patent examiner may determine that the rejection is final. 37 C.F.R. § 1.113. The applicant’s options are then limited to an “appeal in the case of rejection of any claim” or “to [an] amendment” of the application. Id. The RCE is one such amendment. Once a final rejection has issued, the applicant generally has up to six months to file an RCE before the application is abandoned. See 37 C.F.R. § 1.135. An RCE, which may consist of (but is not limited to) “an information disclosure statement, an amendment to the written description, claims, or drawings, new arguments, or new evidence in support of patentability,” functions to continue the examination of the current application by reopening the prosecution. 37 C.F.R. § 1.114(b).
Once the PTO determines that the application contains patentable claims, the PTO will issue a “Notice of Allowance” that informs the applicant that he “is entitled to a patent under the law[.]” 37 C.F.R. § 1.311(a). The applicant must then pay the requisite fees within three months, otherwise the application will be deemed abandoned. Id. Even after the fee has been paid, up until the patent actually issues, the application may be withdrawn by either the PTO or the applicant. 37 C.F.R. § 1.313.
B. Patent Term Adjustments
Subsection 154(b) of Title 35 governs the determination and measurement of PTA. Paragraph (1) of this subsection, entitled “Patent term guarantees,” sets forth three general guarantees designed to expedite the application, prosecution, and examination process. This paragraph also describes the various categories of events that generate PTA, i.e., events that result in the extension of the patent term.
First, subparagraph (A), entitled “Guarantee of prompt Patent and Trademark Office responses,”
Next, subparagraph (B), entitled “Guarantee of no more than 3-year application pendency,” extends the patent term on a day for day basis “for each day after the end of that 3 year period until the patent is issued.” § 154(b)(1)(B). Subparagraph (B) ensures that the patent prosecution and examination process proceeds expeditiously to preserve an approximately 17 year patent term measured from the date of issuance. Certain events, such as time consumed by an RCE or by an applicant requested delay, are “not included” in the measurement, and here the parties disagree as to whether these events are “not included” in the measurement of the three year period (Exelixis’ position) or in the PTA calculation (the PTO’s position).
Finally, subparagraph (C), entitled “Guarantee of adjustments for delays due to interferences, secrecy orders, and appeals,” extends the patent term on a day for day basis for “each day of the pendency of the proceeding, order, or review[.]” § 154(b)(1)(C). Put simply, sub-paragraph (C) grants PTA for time consumed by certain special proceedings that may occur during the course of the prosecution and examination of the application.
The PTA awarded under paragraph (1) is subject to certain limitations set out in paragraph (2), entitled “Limitations.” Subparagraph (A) of paragraph (2) makes clear that “to the extent that periods of delay ... overlap, the period of any adjustment granted under this subsection shall not exceed the actual number of days the issuance of the patent was delayed.” § 154(b)(2)(A).
In this action, Exelixis contends that the PTO improperly calculated B delay by not providing a day for day PTA for time consumed by the RCE filed after the three

A case is ripe for summary judgment where “there ‘is no genuine issue as to any material fact and the moving party is entitled to a judgment as a matter of law.’ ” Wyeth,
IV.
Analysis of the question presented properly begins with the plain language of the statute. As the Supreme Court has noted, “it is axiomatic that ‘[t]he starting point in every-case involving construction of a statute is the language itself.’ ” Landreth Timber Co. v. Landreth,
Here, the plain language meaning of subparagraph (B) is clear, unambiguous, and in accord with both the statute’s structure and purpose. Subparagraph (B) provides in pertinent part,
(i) any time consumed by continued examination of the application requested by the applicant under section 132(b);
the term of the patent shall be extended 1 day for each day after the end of that 3-year period until the patent is issued. 35 U.S.C. § 154(b)(1)(B). Simply put, the goal of this subparagraph, as its title indicates, is a “Guarantee of no more than 3-year application pendency.” It accomplishes this goal by (i) starting a three year clock on the date the application is filed, (ii) tolling the running of this clock if, within the three year period, any of three events occur, including an RCE filing, and (iii) adding a day for day PTA to the patent term for any delay in the issuance of the patent after the three year clock, less any tolling, runs out. Thus, subparagraph (B) essentially describes two calculations. The first is a description of the calculation of the three year period: The three year clock beings to run on the date the application is filed and, except for three specific potential tolling events, including the filing of an RCE, the clock runs continuously until the three year period ends. In other words, the “not including” portion of subparagraph (B), followed by (i), (ii), and (iii), clearly and unambiguously modifies and pertains to the three year period and does not apply to, or refer to, the day for day PTA remedy. Subparagraph (B)’s second calculation is simply a day for day addition to the PTA for every day beyond the end of the three year clock until the patent issues.
Especially notable about this reading of subparagraph (B), which is commanded by the provision’s plain and unambiguous language, is that it does not address the filing of an RCE after the expiration of the three year clock. To be sure, the provision makes clear that the clock is tolled for the processing of an RCE filed before the three year clock runs out, but the provision does not refer to or mention RCE’s filed after the three year clock has run. Instead, subparagraph (B) makes clear that once the three year clock has run, PTA is to be awarded on a day for day basis regardless of subsequent events.
Also notable of subparagraph (B) is that the reading compelled by its plain language is firmly supported by § 154(b)’s structure and purpose. The statute’s purpose is to ensure that an applicant is provided with a PTA remedy for delays in examination and processing attributable to the PTO and to reduce any PTA by delays attributable to the applicant. Significantly, § 154(b) does not treat an RCE filing as applicant delay; instead applicant delay is treated in § 154(b)(2)(C), which is captioned “Reduction of period of adjustment”
In summary, the plain and unambiguous language of subparagraph (B) requires that the time devoted to an RCE serves to toll the running of the three year clock, if the RCE is filed within the three year period; subparagraph (B) does not address RCE’s filed after the running of the three year period nor does it require that the time consumed by an RCE filed after the running of the three year clock be deducted from the PTA. Put simply, RCE’s have no impact on the PTA after the three year deadline has passed
The PTO offers several arguments in support of its interpretation, none of which is persuasive.
Next, the PTO argues that its construction of subparagraph (B) deserves Skidmore v. Swift & Co.,
Finally, the PTO argues that its reading of subparagraph (B) avoids absurd results. Under the PTO’s view, the plain language
V.
In sum, the plain and unambiguous language of subparagraph (B) requires that the time devoted to an RCE tolls the running of the three year clock if the RCE is filed within the three year period. And, put simply, RCE’s have no impact on PTA if filed after the three year deadline has passed. The PTO’s arguments to the contrary are not persuasive and, accordingly, the PTO’s interpretation of subparagraph (B) must be set aside as “not in accordance with law” and “in excess of [its] statutory ... authority” pursuant to 5 U.S.C. § 706(2)(A) and (C). The proper measure of B delay in the present case is from January 15, 2011 (three years after the application filing date) to August 2, 2011 (the date the patent issued). Thus, the B delay PTA for the '622 patent is properly calculated as 199 days.
An appropriate Order will issue.
