Flender Corp. v. Tippins International, Inc.
830 A.2d 1279 (Pa. Super. Ct. 2003)
Pennsylvania Superior Court · 2003
Rule
Under UCC § 2-207, when an offer and acceptance contain conflicting terms on the same subject, both conflicting terms drop out and default rules supply the gap. Forum-selection clauses that disagree are knocked out; jurisdiction is governed by background law.
- Battle of the forms
- UCC § 2-207
- Knock-out rule
Learning outcomes
By the end of working with this case, you can:
- apply UCC § 2-207 to a battle-of-forms problem: conflicting terms on the same subject drop out under the knockout rule and Code gap-fillers control.
- distinguish The common-law mirror-image rule from the UCC's accommodation of imperfect form-on-form acceptances.
- analyze Whether disputed terms are different (knocked out) or additional (analyzed under § 2-207(2)).
Facts
Flender, a German manufacturer of gear-drive assemblies, sold equipment to Tippins. The transaction proceeded through the familiar exchange of pre-printed forms. Flender’s quotation called for arbitration in Vienna; Tippins’s purchase order called for the laws and courts of Allegheny County, Pennsylvania, with no arbitration. When a dispute arose, Tippins sued in Pennsylvania state court, and Flender moved to compel Vienna arbitration.
Holding
The Pennsylvania Superior Court applied UCC § 2-207’s “knock-out” rule. The two forum-selection terms conflicted; under the knock-out approach, neither prevailed, and default jurisdictional rules supplied the gap. The Pennsylvania courts had jurisdiction, and the motion to compel arbitration was denied.
Reasoning
Section 2-207 was drafted to displace the common-law mirror-image rule’s tendency to treat every form mismatch as a counter-offer. Once a contract has been formed by the parties’ conduct or by acceptance with additional or different terms, the question becomes how to reconcile the forms. Pennsylvania, with most jurisdictions, adopts the knock-out rule for conflicting terms: a term in the offer and a contradictory term in the acceptance cancel each other out, leaving the gap to be filled by UCC defaults. That approach refuses to reward the last sender of a form and avoids the trap of treating substantive contract formation as a contest of stationery.
Why it matters
Flender anchors the modern teaching of § 2-207 because it adopts the knock-out rule cleanly and applies it to a high-stakes term, forum selection. Read with State DOT, the chapter contrasts the common-law mirror-image rule and the UCC’s softer treatment of form battles. Together the two cases let students see why Article 2 changed the rules for merchant transactions and what the consequences are for routine commerce conducted by exchanged forms.
The trap
Students apply the 'last shot rule' reflexively, treating whichever form fired last before performance as the controlling document. Article 2 displaces that result. A related trap: students assume conflicting terms cancel only the offeror's, leaving the offeree's. The knockout rule cancels both.
The operational intuition the case is designed to break. Naming the trap is what the Socratic exchange is for.

Surfacing · 60 sec
Q. Your company sends a purchase order for $200,000 of industrial equipment. Your boilerplate says disputes go to your home state's courts. The supplier acknowledges with its own boilerplate sending disputes to arbitration in Vienna. Both sides perform. Then a dispute arises. Where does it go?

Q. What did the Pennsylvania Superior Court do with the two conflicting forum-selection clauses?
Reasoning · 120 sec
Q. At common law, the mirror-image rule would say the seller's acknowledgment was a counter-offer that the buyer accepted by performance, so the seller's terms govern. Article 2 rejects that. Why? And once it does, why don't the seller's terms govern Flender either?
Hypothetical · 90 sec
Vary. Vary one fact. The seller's acknowledgment says: 'Acceptance of this order is expressly conditional upon buyer's assent to the terms herein, including the Vienna arbitration clause.' Buyer takes delivery without signing. Same result?

Q. You have issued a purchase order; your supplier returned an invoice with different boilerplate; the goods shipped. Have you been Flender? What term in your boilerplate would you most want to survive, and how would you draft to protect it?
