IV. Analysis of Infringement Allegations
’310 Patent Infringement Allegations
| Claim Element (from Independent Claim 9) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a housing comprising an intermediate panel set and a cover panel, the cover panel being movably attached to the intermediate panel set | The Liberty meter’s external casing is alleged to consist of a main body (intermediate panel set) and a hinged top portion (cover panel) that opens for service. | ¶35 | col. 2:31-34 |
| a module configured to be removably received by the housing, the module comprising (a) a coin sensor, (b) a card reader, and (c) an electronic device... | The complaint alleges the Liberty meter contains a single, self-contained electronic assembly that includes the payment processing and control electronics, which can be removed as a unit for repair or replacement. | ¶36 | col. 2:66-3:4 |
| ...the electronic device comprising... a solar cell operatively coupled with the rechargeable battery to charge the rechargeable battery, the solar cell being disposed to receive light via the second window | The Liberty meter is alleged to have a rear-facing solar panel that charges its internal battery. This is depicted in a marketing photograph from Defendant's website. (Compl. ¶38, Ex. B). | ¶38 | col. 2:50-54 |
| a card slot in the parking meter front face into which a card is inserted to be read by the reader | The complaint alleges the front of the Liberty meter has a slot for inserting credit and debit cards for payment. | ¶40 | col. 3:3-5 |
- Identified Points of Contention:
- Scope Questions: A central question is whether the Liberty meter's internal architecture constitutes a single "module configured to be removably received" in the specific manner described in the patent, which depicts a distinct unit sliding into the housing (ʼ310 Patent, Fig. 5). The defense may argue its design is integrated differently.
- Technical Questions: The complaint's ability to proceed on this patent is questionable given the IPR certificate cancelling claim 9. The analysis will depend entirely on whether any legal avenue exists to overcome this cancellation, an issue that would be addressed in dispositive motions.
’054 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A parking meter device that is receivable within a housing base of a single space parking meter | The complaint alleges the Liberty meter is designed and marketed as a device that can be installed into existing, standard parking meter housing bases, thereby upgrading legacy infrastructure. | ¶45 | col. 3:32-38 |
| a payment facilitating arrangement operable in cooperation with a non-cash payment medium | The Liberty meter's credit/debit card reader is alleged to be the claimed payment facilitating arrangement. | ¶47 | col. 1:8-11 |
| a wireless communications subsystem configured to receive information relating to the non-cash payment medium | The complaint alleges the Liberty meter contains a cellular modem for wirelessly transmitting credit card transaction data for authorization. | ¶48 | col. 1:25-30 |
| wherein the lower portion of the parking meter device is configured... such that the lower portion is receivable within the housing base... and wherein the upper portion... is covered by a cover that is configured to accommodate the upper portion | The Liberty meter is alleged to have a two-part physical design, with a lower body that fits into a standard housing and an upper electronics head that is enclosed by a corresponding cover. | ¶51 | col. 5:6-19 |
- Identified Points of Contention:
- Scope Questions: The infringement analysis may turn on the term "receivable within a housing base." Does this limit the claim to devices sold exclusively as retrofit kits, or does it also cover complete meter assemblies that are merely compatible with standard bases? The complaint's evidence on how the Liberty meter is marketed and sold will be critical.
- Technical Questions: What evidence does the complaint provide that the Liberty meter is specifically designed for retrofitting into a "conventional" housing base (ʼ054 Patent, col. 1:20-21), as opposed to being a new product with its own proprietary housing?
V. Key Claim Terms for Construction
Term: "module configured to be removably received" (’310 Patent, Claim 9)
- Context and Importance: The definition of "module" is critical. Infringement depends on whether the accused meter's electronics are arranged as a single, removable unit that corresponds to the patent's specific modular concept, or if they are integrated in a materially different way.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification describes the "module 32" in general terms as including an "electronic device 33" and a "coin sensor 34" (ʼ310 Patent, col. 2:66-3:4), which could be argued to encompass any physically consolidated electronics package.
- Evidence for a Narrower Interpretation: Figure 5 explicitly shows the module (32) as a distinct, cassette-like component being inserted into a body (36). The text describes it as being "received within a slot 37 of the body 36" (ʼ310 Patent, col. 3:1-4), which suggests a specific physical form factor and method of removal, potentially narrowing the term's scope.
Term: "receivable within a housing base of a single space parking meter" (’054 Patent, Claim 1)
- Context and Importance: This term appears to be the central limitation defining the invention as a retrofit device. The case may hinge on whether the accused product is sold for this purpose. Practitioners may focus on this term because it links the claimed device to a specific context of use—upgrading existing infrastructure.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party could argue the term simply means the device is physically dimensioned to be capable of fitting into a standard housing base, regardless of how it is marketed or sold.
- Evidence for a Narrower Interpretation: The patent’s abstract and detailed description repeatedly frame the invention as a solution for retrofitting "conventional single space parking meter housing[s]" (ʼ054 Patent, Abstract; col. 1:19-24). The phrase "upgrading an existing parking meter" is used to describe the invention's method (ʼ054 Patent, col. 1:66-67), strongly suggesting the term implies a device intended for that specific purpose.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Defendant induces infringement by providing its municipal customers with technical specifications, installation guides, and user manuals that instruct them to operate the accused Liberty meters in a manner that directly infringes the patents-in-suit (Compl. ¶58).
- Willful Infringement: The complaint alleges that Defendant’s infringement has been willful and deliberate, asserting that Defendant had pre-suit knowledge of the patents and the infringing nature of its products. This assertion is made to support a claim for enhanced damages (Compl. ¶62).
VII. Analyst’s Conclusion: Key Questions for the Case
- Procedural Viability: A threshold issue for the court will be the effect of the IPR certificate that cancelled all asserted independent claims of the '310 patent after the suit was filed. Can the infringement count based on this patent survive, or is it moot?
- Definitional Scope and Intended Use: For the '054 patent, a core question is one of scope: is the claim limitation "receivable within a housing base" met by any compatible product, or is it narrowed by the specification's focus to cover only devices marketed and sold specifically as retrofit kits for upgrading existing meter infrastructure?
- Structural Equivalence: Should the '310 patent claim proceed, a key evidentiary question will be one of structural correspondence: does the accused meter's integrated electronics package meet the specific "removable module" limitation of Claim 9, or does its architecture represent a distinct, non-infringing design?
