Identified Points of Contention
- Scope Questions: For the ’054 Patent, a central issue may be the construction of "receivable within a housing base." The dispute could turn on whether the accused product is merely a replacement meter that fits a standard post, or if it functions as a true "retrofit" device for an existing housing assembly as the patent's specification appears to emphasize (’054 Patent, col. 3:39-41).
- Technical Questions: The complaint's infringement allegations rely on high-level product features described in sales proposals (Compl. ¶¶ 28, 43). A key question for the court will be whether the accused product's internal components, such as its "power management facility" (Compl. ¶31d) or "telephone connection" (Compl. ¶46c), actually operate in the specific manner required by the detailed claim language, or if there is a technical mismatch.
V. Key Claim Terms for Construction
Term 1: "receivable within a housing base of a single space parking meter" (’054 Patent, Claim 1)
- Context and Importance: This phrase is foundational to the ’054 Patent's narrative of retrofitting and upgrading existing infrastructure. The infringement analysis for the entire device may depend on whether the accused product meets this structural limitation. Practitioners may focus on this term because it distinguishes a mere replacement from an integrated upgrade kit.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself does not explicitly require the pre-existence of a specific, complete housing. One could argue it reads on any device with a form factor designed to fit into a standard meter base, new or old.
- Evidence for a Narrower Interpretation: The specification repeatedly frames the invention in the context of upgrading existing meters, stating the device is "receivable in a housing base of an existing installed parking meter" and describing a "method of upgrading an existing parking meter." (’054 Patent, col. 3:39-41, col. 2:65-3:7). This could support a narrower construction requiring the base to be part of a pre-existing installation.
Term 2: "telephone connection" (’310 Patent, Claim 1)
- Context and Importance: This term defines the meter's remote communication capability, a key feature for modern management. Its scope is critical to determining whether the accused product's wireless technology infringes, especially given the evolution of wireless protocols since the patent's priority date.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification provides "mobile (cellular) telephone" as an example, suggesting "telephone connection" is not strictly limited to cellular technology but could encompass other wireless data links that achieve the same function of transmitting payment information. (’310 Patent, col. 3:30-31).
- Evidence for a Narrower Interpretation: A party could argue that in the 2007-2008 timeframe, a "telephone connection" implied specific network architectures (e.g., circuit-switched) and that modern, purely IP-based systems fall outside the term's ordinary meaning as understood at the time.
VI. Other Allegations
- Indirect Infringement: The complaint alleges both induced and contributory infringement for both patents. The inducement claims are based on allegations that Duncan provides training, support manuals, and advertising that instruct and encourage customers to use the accused meters in an infringing manner (Compl. ¶¶35, 50). The contributory infringement claims are based on allegations that the accused meters and their spare parts are especially made for infringing use and have no substantial non-infringing uses (Compl. ¶¶37, 52).
- Willful Infringement: The complaint alleges willful infringement of both patents based on pre-suit knowledge. For the ’310 Patent, knowledge is alleged as of October 9, 2012, based on Duncan citing the patent in an IDS for its own application (Compl. ¶21, ¶56). For the ’054 Patent, knowledge is alleged as of May 14, 2014, also based on an IDS filing (Compl. ¶23, ¶41). The complaint includes a table summarizing Duncan's alleged pre-suit knowledge by listing its patent applications that cited the patents-in-suit (Compl. p. 7, ¶24). This table serves as a visual depiction of the factual basis for the willfulness claim.
VII. Analyst’s Conclusion: Key Questions for the Case
- A threshold question for the second cause of action concerns case viability: given that the asserted independent claim of the ’310 Patent was cancelled in an IPR proceeding after the complaint was filed, it raises the question of what legal basis, if any, remains for this count and whether Plaintiff can successfully amend its allegations to proceed on any surviving claims.
- A core issue for the ’054 Patent will be one of definitional scope: can the claim term "receivable within a housing base," which is tied to the patent's retrofitting concept, be construed to read on the accused Duncan Liberty® meter, or can the product be successfully distinguished as a complete replacement unit that falls outside the scope of the claims?
- A key evidentiary question across both asserted patents will be one of functional proof: beyond the high-level product descriptions cited, what technical evidence will be presented to establish that the accused product's internal systems perform the specific functions recited in the detailed claim limitations, such as those for the "power management facility" and "wireless communications subsystem"?
