The Orange Guide Transparency Act primarily codifies present FDA practices, however provides a brand new requirement for delisting patents invalidated by the Patent Trial and Enchantment Board of the USPTO. The Purple Guide Persevering with Act codifies a variety of FDA’s present Purple Guide practices, and imposes a brand new requirement for publishing the reference product sponsor’s “patent lists” exchanged within the so-called “patent dance” of BPCIA biosimilar litigation.
The Orange Guide Transparency Act
The Orange Guide Transparency Act (Pub. Regulation. 116-290) codifies the follow of itemizing patents within the Orange Guide that declare the drug at situation (drug substance or formulation patents) and/or that declare a way of utilizing the drug for the indication(s) at situation. The Act offers the next time durations for submitting patent info to FDA, relying on when the patent is granted:
With the 505(b)(1) utility
Inside 30 days of approval of the 505(b)(1) utility
Inside 30 days of grant of the patent
The Act doesn’t specify any stand-alone penalties for “late” itemizing or failing to listing a patent.
The Act imposes a brand new requirement for delisting patents invalidated by the Patent Trial and Enchantment Board of the USPTO (e.g., in an Inter Partes Assessment or Put up Grant Assessment continuing). The delisting requirement applies to “a closing determination issued by the Patent Trial and Enchantment Board … or by a court docket, from which no enchantment has been, or could be, taken,” if the results of the choice is that the patent now not meets the itemizing necessities (e.g., if all related claims had been invalidated).
The Act requires the NDA holder to inform FDA in writing, inside 14 days of the choice and to offer a duplicate of the choice to FDA. The Act requires FDA to delist the patent, however not earlier than the expiration of any pending 180-day exclusivity interval stemming from a paragraph (IV) certification in opposition to the patent.
The brand new delisting requirement “applies solely with respect to a call … issued on or after the date of enactment of this Act,” which was January 5, 2021.
The Purple Guide Continuity Act
The Purple Guide Continuity Act is a part of the Omnibus Appropriations Invoice enacted December 27, 2020, in Part 325 entitled “Organic Product Patent Transparency.” Just like the Orange Guide Transparency Act, the Purple Guide Continuity Act codifies present FDA Purple Guide practices, but additionally imposes a brand new patent itemizing requirement.
Particularly, the Act add a brand new paragraph (9) to 42 U.S.C. 262(ok), entitled “PUBLIC LISTING.” The provisions requires FDA to publish an inventory of accepted organic merchandise, their date of licensure and utility quantity, their licensure and advertising and marketing standing, and any regulatory exclusivity durations, and to replace the listing each 30 days.
The patent itemizing requirement comes below (9)(A)(iii), entitled “PATENT INFORMATION,” which states:
Not later than 30 days after an inventory of patents below subsection (l)(3)(A), or a complement to such listing below subsection (l)(7), has been offered by the reference product sponsor to the subsection (ok) applicant respecting a organic product included on the listing printed below this subparagraph, the reference product sponsor shall present such listing of patents (or complement thereto) and their corresponding expiry dates to the Secretary, and the Secretary shall, in revisions made below clause (ii), embrace such info for such organic product.

As enacted, the Purple Guide Continuity Act is considerably extra conservative than the Organic Patent Transparency Act that was launched by Sen. Collins (R-Maine) in 2019. As mentioned in this article, that Act would have imposed a forward-looking patent itemizing requirement much like that of the Orange Guide.
Extra Transparency However Not Consistency
Whereas each the Orange Guide Transparency Act and the Purple Guide Persevering with Act require FDA to publish patents referring to accepted merchandise, the acts maintained the totally different patent itemizing paradigms that apply to medication versus biologics. Whereas 505(b)(1) candidates should establish related patents up entrance, BLA holders want solely establish patents if and when they’re included on a “patent listing” throughout the “patent dance” stage of biosimilar litigation below the BPCIA. Whereas the Orange Guide consists of solely drug product and methodology of use patents, the Purple Guide may embrace methodology of manufacture patents, however solely these which have been raised in opposition to a particular biosimilar applicant. Thus, rivals in search of to develop generic drug or biosimilar merchandise will nonetheless have to undertake their very own patent searches to establish doubtlessly related patents that aren’t required to be listed.
