eCardless Bancorp, Ltd. v. PayPal Holdings, Inc.
5:24-cv-01054
| N.D. Cal. | Nov 14, 2024Background
- eCardless Bancorp brought suit against PayPal, alleging infringement of four expired patents related to secure online transaction methods (patents ’862, ’863, ’206, and ’942).
- The patents discuss innovative systems for verifying, authorizing, and processing Internet transactions, with a focus on preventing interception or fraud.
- The parties participated in a claim construction tutorial and Markman hearing; multiple claim terms (agreed and disputed) were presented for construction.
- Key factual disputes centered on the technological meaning of terms like “transaction identifier,” “order variable,” and the procedural steps for device/location verification in online transactions.
- The court addressed both standard claim construction and challenges based on indefiniteness under 35 U.S.C. § 112, ¶ 2, focusing on whether claims adequately inform skilled artisans of their scope.
Issues
| Issue | Plaintiff’s Argument | Defendant’s Argument | Held |
|---|---|---|---|
| Construction of “transaction identifier” | Not clearly limited by prosecution; could be created by bank | Prosecution disclaimer: only customer/merchant can create | “Transaction identifier” cannot be created by bank; only customer, merchant, or both |
| "Said ... at least one order variable" | Refers to an order field, not necessarily same as prior step | Must derive antecedent basis from previous limitation | Construed as "field of information included in an order file" |
| Construction of “authorized location” | Includes third-party associated locations, not just party accounts | Must be associated with customer/merchant account | Includes comparing device location to any stored authorized location |
| “Communicating . . . including transaction identification” | Plain meaning; accepts possible multiple identifiers | Indefinite for lack of clear antecedent basis | Indefinite: claim fails to identify which identifier is referenced |
