Plaintiff, OPINION AND ORDER vs. Re: DEFENDANT’S MOTION FOR JUDGMENT AVERY DENNISON CORPORATION, AS A MATTER OF LAW UNDER RULE 50(b) AND MOTION FOR RELIEF FROM JUDGMENT Defendant. UNDER RULE 60(b)

KASUBHAI, United States Magistrate Judge: Defendant Avery Dennison renews its motion for judgment as a matter of law under Rule 50(b) and requests relief from judgment from prior rulings under Rule 60(b). See generally Def.’s Mot. J. Matter Law & Mot. Relief from J., ECF No. 591 (“Def.’s JMOL”). Specifically, Defendant asserts that claim 1 of U.S. Patent No. 9,798,967 (the “‘967 patent”) is invalid because it is (1) directed to ineligible subject matter under 35 U.S.C. §101; and (2) anticipated by U.S. Patent No. 7,857,221 (the “Kuhno patent”) under 35 U.S.C. § 102. Id. at 3–13, 19–26. In the alternative, Defendant moves for the Court to alter or amend the judgment under Rule 59(e).

Id. at 26. Both parties consent to jurisdiction by a U.S. Magistrate Judge. ECF No. 29. For the reasons described below, Defendant’s motion is DENIED. BACKGROUND I. General Background The ’967 patent relates, in part, to methods and systems for commissioning radio- frequency identification (RFID) transponders. ’967 patent at 3:27–32. RFID transponders, also known as RFID tags, are used, like barcodes, to identify and track objects by encoding data electronically in a compact label. Id. at 1:32–34. But unlike traditional barcodes, RFID tags need not include external, machine-or human-readable labels and can communicate the data they

encode over a distance using radio-frequency transmission. Id. at 1:34–53, 6:28–59. To facilitate identifying and tracking an object in the stream of commerce, RFID tags are encoded with information associated with the object through a process known as “commissioning.” Id. at 1:40–53. The encoded data may include various categories of information, “for example, data representing an object identifier, the date-code, batch, customer name, origin, destination, quantity,” etc. Id. at 1:45–50. Regardless of the specific categories included, to ensure accurate tracking, it is critical that the data uniquely identify the tagged object. Id. at 2:21–22, 2:48–50. In the RFID industry, uniqueness is ensured by assigning RFID tags an Electronic Product Code (EPC or EPCglobal) in accordance with certain global formatting standards. An EPC is a serialized object number comprising object class information and a serial number that together uniquely identify the associated object. See id. at 9:7–15. For example, the EPC may be a Serialized Global Trade Item Number (SGTIN), which consists of a Global Trade Item

Number identifying the brand and class of the item (i.e., object class information) followed by a serial number uniquely identifying the tagged item within the brand and class. Id. Since objects from the same brand and class will share the same object class information, ensuring the uniqueness of the overall EPC amounts to ensuring uniqueness of the serial number. Ensuring uniqueness, however, is not necessarily straightforward. Id. at 2:49–50. Serialization generally “requires a central issuing authority of numbers for manufacturers, products, and items to guarantee uniqueness and to avoid duplication of numbers.” Id. at 2:23– 25. The issuing authority assigns blocks of numbers to remote locations, wherein each remote location receives the numbers one by one or where the numbering space is partitioned in some

manner. Id. at 2:25–29. But, in either case, the encoded numbers must generally be reconciled by comparison to a central database “either one or several numbers at a time.” Id. at 2:30–32. In the case of EPCglobal numbers, the central issuing authority is known as GS1. Id. at 7:61–65, 9:7–15. GS1 distributes blocks of numbers to member companies in a hierarchical manner, wherein each company is authorized to then “further allocate numbers from its upper level database to as many lower database levels as it deems necessary to distribute number authority throughout its enterprise.” Id. at 7:61–8:3. Using central databases to distribute the allocated numbers has certain drawbacks. It generally requires encoders to maintain a continuous network connection with the database so that new serial numbers can be retrieved when an RFID tag is commissioned. See id. at 3:27–4:4. But a continuous connection is not always possible and, even when it is, may be plagued by network delays that slow down the commissioning process. See id. at 3:64–4:4. This in turn may delay or impair downstream activity, including manual steps in the commissioning or distribution process. Id.

The ’967 patent seeks to “overcome[ ] these shortcomings” using systems and methods for commissioning RFID tags “on-demand” and “with no external authorizations or queries required on a transponder-by-transponder basis,” enabling commissioning to proceed without the need for continuous connectivity to a central database. Id. at 3:27–35, 3:64–67. In one embodiment, pre-authorized ranges of serial numbers for specific object classes are allocated to lower levels in the hierarchy, for example, individual encoders. Id. at 8:4–11. In this embodiment, the object class serial number space is subdivided into sectors defined by a series of fixed “Most Significant Bits” (MSBs), wherein the number of allocatable sectors is determined by the number of MSBs. Id. at 8:11–15. For example, according to the SGTIN-96 standard, the serial number space consists of 38 bits which can encode 238 distinct serial numbers. If the first

14 of these bits are designated as MSBs, then the serial number space is correspondingly subdivided into 214 sectors or “blocks” which can be allocated to as many as 214 different encoders. See id. at 8:21–29. The remaining 24 bits can then be used to encode a unique serial number space within a given block. Id. “Each allocated block of serial numbers represents authority for encoding objects of an object class that can either be used by an encoder for encoding transponders, or allocated to a lower level in the authority hierarchy.” Id. at 8:32–36. Critically, once a block is allocated to an encoder, there is no need to reconnect to a central database until the unique numbers within the block have been exhausted. See id. at 8:37– 51. Thus, in the previous example, 224, or approximately 16.8 million, RFID tags could be commissioned before reconnection to a central database is required. And by eliminating the need for a continuous connection to the database, the attendant delays are reduced and the commissioning process is improved. The ’967 patent refers to such a system, where only intermittent connection to a central database is necessary, as quasi-autonomous encoding
