Before D YK , T ARANTO , and H UGHES , Circuit Judges.

D YK , Circuit Judge.
Victoria’s Secret Direct Brand Management, LLC (“Victoria’s Secret”) and Avon Products, Inc. (“Avon”) (collectively, “ defendants ”) appeal from a judgment of the District Court for the Eastern District of Texas . The district court found that defendants infringed claims 34 and 51 of U.S. Patent No. 5,715,314 (the “’314 patent ”) and claims 15, 17, and 39 of U.S. Patent No. 5,909,492 (the “’492 patent ” ) and that those claims were not invalid.
After the district court’s judgment

, this court decided Soverain Software LLC v. Newegg Inc.

, 705 F.3d 1333 (Fed. Cir. 2013)

, amended on reh’ g , 728 F.3d 1332, 1336 (Fed. Cir. 2013) (hereinafter “ Newegg ”). There , we held invalid as obvious claims 34 and 51 of the ’314 patent and claims 17, 41, and 61 of the ’492 patent. Id. at 1341, 1344. We hold that issue preclu sion applies as a result of the Newegg case, and that the asserted claims here are ther efore invalid. Accordingly, we reverse.

B ACKGROUND Soverain Software LLC (“Soverain ” ) is the assignee of the ’314 and ’492 patents

. It brought an infringement action against defendants in the Eastern District of Texas

. The asserted claims fall into two categories. Claims 34 and 51 of the ’314 patent and claim 17 ofSOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 3

the ’492 patent are directed to virtual shopping carts. 1 Claims 15 and 39 of the ’492 patent are directed to using

1 Claim 34 of the ’314 patent is representative. It recites:

A network

- based sales system, comprising: at least one buyer computer for operation by a u ser desiring to buy products; at least one shopping cart computer; and a shopping cart database connected to said sho pping cart computer; said buyer computer and said shopping cart co mputer being interconnected by a computer network; said buyer computer being programmed to re ceive a plurality of requests from a user to add a plurality of respective products to a shopping cart in said shopping cart database, and, in response to said requests to add said products, to send a plurality of respective shopping cart messages to said shopping cart computer each of which comprises a product identifier ident ifying one of said plurality of products; said shopping cart computer being programmed to receive said plurality of shopping cart me ssages, to modify said shopping cart in said shoppi ng cart database to reflect said plural ity of requests to add said plurality of products to said shopping cart, and to cause a payment message associated with said shopping cart to be created; and said buyer computer being programmed to receive a request f rom said user to purchase said pl urality of products added to said shopping cart and to cause said payment message to be act ivated to initiate a payment transaction forSOVERAIN SOFTWARE LL C v.

2 Claim 15 of the ’492 patent is representative. It recites:
A hypertext statement system, comprising: a client computer for operation by a client user; and one or more server computers f or operation by a

server user; the client computer and the server computers b eing interconnected by a public packet switched computer network; at least one of the server computers being pr ogrammed to record information pertaining to purchase transaction re cords in a database, and to transmit a statement document co mprising the purchase transaction records to the client computer over the network; the client computer being programmed to display the statement document to receive a request from the client user to display transaction d etails corresponding to a portion of the stat ement document displayed by the client computer, and to cause a transaction detailSOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 5

On November 18, 2011, a jury determined that defendants infringed the asserted claims and that those claims were not invalid as anticipated or obvious. The district court subsequently entered judgment in favor of Soverain

. Defendants appealed on September 7, 2012.
Subsequent to the filing of the appeal , on January 22, 2013, this court decided Newegg

, a case from the Eastern District of Texas in which Soverain also alleged infring ement of the ’314 and ’492 patents. The re, the district court had entered judgment that the asserted claims were infringed and not invalid. On ap peal , we reversed, holding invalid as obvious claims 34 and 51 of the ’314 patent and claims 17, 41, and 61 of the ’492 patent. Newegg , 705 F.3d 1333 at 1347

. In a subsequent panel rehearing decision, we clarified that claim 35 is also invalid. We “ confirm[ed] that claim 34 is representative of the ‘shopping cart’ claims, including claim 35, and conclude[d] that depen den t claim 35 is invalid on the ground of obviousness.” Soverain Software LLC v. Newegg Inc.

We apply the law of the regional circuit to the general procedural question of whether issue preclusion applies. RF Del., Inc. v. Pac. Keystone Techs., Inc. , 326 F.3d 1255

, 1261 (Fed. Cir. 2003). W e apply this court’s precedent to questions involving subst antive issues of patent law

, issues of issue preclusion that implicate substantive patent law issues, or issues of issue preclusion that impl icate the scope of our own previous decisions

. Ohio Willow Wood Co. v. Alps S., LLC

, 735 F.3d 1333, 1342 (Fed. Cir. 2013) (citing Aspex Eyewear, Inc. v. Zenni Optical Inc.

, 713 F.3d 1377, 1380 (Fed. Cir. 2013)). “[T]he issue of whether to apply collateral estoppel is a question of law, making our review de novo .” Bradberry v. Jefferson C n ty., Tex. , 732 F.3d 540, 549 (5 th Cir. 2013) (citation omitted)

. D ISCUSSION

I
The first question is whether issue preclusion , or co llateral estoppel, should apply to claims 34 and 51 of the ’314 patent and claims 15 and 17 of the ’492 patent as a result of the Newegg judgment

. “Issue preclusion pr ohi b its a party from seeking another determination of the litigated issue in the subsequent action.” State Farm Mut. Auto. Ins. Co. v. LogistiCare Solutions, LLC , 751 F.3d 684, 689 (5th Cir. 2014) (quoting United States v. Shanbaum

, 10 F.3d 305, 311 (5th Cir. 1994)). The Fifth Circuit a pplies issue preclusion where the following four conditions are satisfied:
First, the issue under consideration in a subs equent action must be identical to the issue litiga ted in a prior action. Second, the issu e must have

claim 34. This court granted rehearing, to assure that the claims at issue in th[e] litigation were adequately and fairly assessed at trial and on appeal.” Newegg II , 728 F.3d at 1333.SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 7

been fully and vigorously litigated in the prior a ction. Third, the issue must have been necessary to support the judgment in the prior case. Fourth, there must be no special circumstance that would render preclusion inappropriate or unfair.

Id

. (quoting Shanbaum , 10 F.3d at 3 11). Our own law is similar. Jet, Inc. v. Sewage Aeration Sys.

, 223 F.3d 1360, 1366 (Fed. Cir. 2000) (issue preclusion requires four conditions: “(1) identity of the issues in a prior proceeding; (2) the issues were actually litigated; (3) the determin ation of the issues was necessary to the resulting jud gment; and , ( 4) the party defending against preclusion had a full and fair oppor tunity to litigate the issues ” (citations omitted) ).

In Newegg , we explicitly held that claims 34 and 51 of the ’314 patent and claim 17 of the ’492 patent were obvious. 705 F.3d at 1341. A lthough claim 15 of the ’492 patent , at issue here, was not explicitly invalidated in Newegg , we invalidated claim 41, which depends from claim 15. Id. at 1344. Therefore, the invalidity determin ation as to claim 41 extended to claim 15 , as well

. See Calla way Golf Co. v. Acushnet Co. , 576 F.3d 1331, 1344 (Fed. Cir. 2009) (“A broader independent claim cannot be nonobvious where a dependent claim stemming from that independent claim is invalid for obviousness .”) (citation omitted)

. T he Supreme Court has held that a defense of issue preclusion applies where a party is “facing a charge of infringement of a patent that has once been declared invalid,” even though the party asserting the defense was not a party to the action where the patent was invalida ted

. Blon der

- Tongue Labs., Inc. v. Univ. of Ill. Found. , 402 U.S. 313, 349

– 50 (1971). We have similarly held that “once the claims of a patent are held invalid in a suit involving one alleged infringer, an unrelated party who is sued for infringement of those claim s may reap the ben e-SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 8

fit of the invalidity decision under principles of collateral estoppel.” Mendenhall v. Barber

- Greene Co. , 26 F.3d 1573, 1577 (Fed. Cir. 1994); see In re Cygnus Tele comms

. Tech., LLC, Patent Litig. , 536 F.3d 1343, 1349 (Fed. Cir. 2008) ; P

harmacia & Upjohn Co. v. Mylan Pharm., Inc. , 170 F.3d 1373, 1379 (Fed. Cir. 1999)

. It is also established that issue preclusion applies even though the precluding judgment ( Newegg ) comes into existence while the case as to which preclusion is sought (this case) is on appeal. Mendenhall

, 26 F.3d at 1583

– 84 (invalidity decision rendered while case on appeal) ; Dana Corp. v. NOK, Inc.

, 882 F.2d 505, 508 (Fed. Cir. 1989) (invalidity decision at Federal Circuit issued while case being briefed on appeal)

. As to the four claims listed above, Soverain agrees that issue preclusion would normally be applicable but argues that it should not apply here because Soverain has not had a full and fair opportunity to litigate the issue of obviousness.

Under i ssue preclusion law generally and under both our law and F ifth Circuit law, a judgment of invalidity will not have a preclusive effect if a patentee can demo nstrate that it did not have a full and fair opportunity to litigate the issue. Blumcraft of Pittsburgh v. Kawneer Co.

, 482 F.2d 542, 546

– 47 (5th Cir. 1973); see Blonder

- Tongue

, 402 U.S. at 333 (a patentee “must be permitted to demo nstrate, if he can, that he did not have ‘a fair opportunity procedurally, substantively and evidentially to pursue his claim the first time’” (citation omitted) ); Pharmacia , 170 F.3d at 1379 ( “[A] judgment of invalidity will have no collateral estoppel effect if the patentee can show that it did not have a full and fair opportuni ty to litigate.”); Restatement (Second) of Judgments § 28(5) (1982) (a party is not precluded where “the party sought to be precluded, as a result of the conduct of his adversary or other special circumstances, did not have an adequate opportunity or incentive to obtain a full and fair adjudic ation in the initial action”)

.SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 9

We need not here review the various grounds that are relevant to whether a party had a full and fair opportun ity to litigate because most are inapplicable here

. See generally Blonder

- Tongue , 402 U.S. at 332

– 34; Restat ement (Second) of Jud gments §§ 28, 29. For example , the issue of incentive to litigate arises where “[t]he stakes in the first action may be so small that extensive effort is not reasonable if the risk is limited to the first action.” 18 Charles Alan Wright, Arthur R. Miller & Edward H. Cooper, Federal Practice & Procedure § 4423 (2d ed. 2002). That circumstance does not exist here. Soverain does not dispute that it was represented by distinguished counsel in that appeal and that the amount in controversy was significant.

The u nusual full and fair opportunity argument made here requires an understanding of the appeal i n Newegg

. In the district court in Newegg , at the close of evidence, Soverain and the defendant Newegg Inc. (“Newegg”) filed

cross -motion s for judgment as a matter of law (“ JMOL ”) ; the district court granted Soverain’s JMOL motion of non

obviousness and denied Newegg’s JMOL motion of obv iousness

. See Newegg , 705 F.3d at 1336. As a result of the grant of Soverain’s motion, the jury did not address obviousness. Id.

A fter the jury’s verdict, the district court denied Newegg’s renewed JMOL motion and a lternative motion for a new trial. Id. Newegg appealed from the district court’s judgment of non -obviousness. Id

. W hile Newegg had preserved in the district court the argument that it should have been granted JMOL on the issue of obviou sness, on appeal Newegg explicitly argued only that the district court erred in granting JMOL for Soverain on the issue of non

- obviousness and in not granting Newegg’sSOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 10

motion for a n ew trial

. 4 See id. Newegg also requested “any other and further relief to which it may be justly entitled.” J.A. 37701.
We acknowledged that Newegg on appeal had argued only for a new trial but noted that, “[h]owever, questions of law must be correctly de cided

. . . .” Newegg , 705 F.3d
at 1337. On “th[o]se premises, we determine[d] the que stion of obviousness.” Id. The primary evidence before us in Newegg regarding invalidity was the “CompuServe Mall” system, a prior electronic commerce system , including two books describing the system which disclosed the use of electronic shopping carts

. Id. at 1337 –3 8, 134 0–4 1, 1343

– 44

. Soverain’s arguments for nonobviousness relied on features that were either “not embodied in the claims and not reflected in the claim c onstruction,” id. at 1339; see id.
at 1341, or related to incorporation of known internet technology, id. at 1340, 1343

– 44

. Soverain petitioned for rehearing and rehearing en banc. Soverain argued that the court improperly ordered JMOL when, on appeal, New egg had asked only for a new trial. Additionally, Soverain and Newegg both noted that claim 35 of the ’314 patent had not been addressed in our decision, even though it had been included in the district court’s judgment of no invalidity

. We subsequently gr an t4 Newegg was thus unlike Un itherm Food Sys tems
, Inc. v. Swift

- Eckrich, Inc ., 546 U.S. 394, 398 (2006) (hol ding “that since respondent failed to renew its preverdict motion as specified in Rule 50(b), there was no basis for review of respondent's sufficiency of the evidence cha llenge in the Court of Appeals”). The Su preme Court has recognized that, under Federal Rule of Civil Procedure 50, a court of appeals can direct entry of judgment in cases where the sufficiency of the evidence is challenged , and a JMOL motion was made in the dis trict court

. See Neely v. Martin K. Eby Constr. Co. , 386 U.S. 317, 328

ed panel rehearing and , after considering supplemental briefing and arguments, “confirm[ed] that claim 34 is representative of the ‘shopping cart’ claims, including claim 35, and conclude[d] that dependent claim 35 is inval id on the ground of obviousness.” Newegg II , 728 F.3d at 1336. We implicitly rejected the patentee’s arg ument that the court should have granted a new trial rather than JMOL, id. , implic itly rejecting the idea that Soverain did not have a full and fair opportunity to lit igate

. R ehearing en banc was denied

. Soverain Software LLC v. Newegg Inc. , No. 2011

- 1009 (Fed. Cir. Sept. 4, 2013) (order denying en banc rehearing). Soverain’s petition for a writ of certiorari to the Supreme Court was denied. Soverain Software LLC v. Newegg I nc. , 134 S. Ct. 910 (2014).
We note that Soverain does not argue that it was d eprived of crucial evidence or witnesses in the first litig ation or that it would present additional evidence at a new trial. See Blonder

- Tongue , 402 U.S. at 333. Nor is there any contention that Soverai n did not have a full and fair opportunity to litigate the question of obviousness at the district court. Rather, Soverain’s argument is that it did not have the incentive to fully litigate the issue of non

obviousne ss on appeal

. 5

5 Soverain also argues that it lacked the ability to

ap peal our judgment in Newegg , under the exception to preclusion which applies where a party “could not, as a
matter of l aw , have ob tained review of the judgment in the initial ac tion. ” Restatement (Second) of Judgme nts § 28(1). But the ability to appeal generally concerns the ability to appeal from the court of first instance (here, the district court) . And here, Soverain p etitioned for rehea ring and to the Supreme Court for certiorari. The ability to appeal exception “applies only when review is precluded as a matter of law. It does not apply in cases where reviewSOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 12

Specifically, Soverain contends that it would have raised different or additional arguments on appeal if it had known that this court might reverse the district court on invalidity rather than only grant ing a new trial. But Soverain does no t ci te any case to support the notion that a full and fair opportunity to litigate is lacking where a party might have argued different ly on appeal. In Newegg

, t he same basic issue of obviousness was central whether the focus was on insufficiency of the ev idence as a ground for JMOL or on insufficiency of the eviden ce as a ground for a new trial. Not surprisingly

, Soverain has not identified any significant new arguments that were no t in fact raised in the earlier appeal

. With respect to the shopping cart patents (claims 34 and 51 of the ’314 patent and claim 17 of the ’492 patent), Soverain argues that it did not have a full and fair oppo rt unity to present its arguments in Newegg that “ product identifiers, ” a limitation in each of the asserted claims, distinguish the prior art CompuServe Mall system. Bas ically, a product identifier identifies which product a user has placed in a shopping cart. 6 See ’314 patent col. 3 ll. 45

– 47, col. 5 ll. 29

– 30, col. 14 ll. 9

– 10. But Sovera in presented the same arguments about product identifiers in Newegg that it puts forward here . Here, Soverain points to expert testimony to argue that the CompuServe Mall system did not utilize product identifiers because that system was a single computer system that always recognized the identity of the user and which product the user was viewing. Similarly, i n Newegg

, Soverain co ntended that “Newegg’s fact witness, Mr. Trevor, testified

is available but is not sought. Nor does it apply when the re is discretion in the reviewing court to grant or deny review and review is denied

. . . .” Id. § 28 cmt. a.

6 The term “product identifier ” was not construed at the district court.SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 13

that t he CompuServe Mall did not employ product ident ifiers, and was therefore not programmed to send shopping cart messages

. . . each of which comprises a product identifier.” Brief of Plaintiff

- Appellee Soverain Software LLC at 45, Newegg , 705 F.3d 1333 (No. 2011

- 1009) (alte rations in original) ( internal quotation marks and citation omitted). Soverain argued that , “[a]s Soverain’s expert, Dr. Shamos, explained, the basic architecture of the CompuServe Mall was specifically designed so that the system would be able to ascertain which products the customer had selected for purchase without the use of a separate product identifier. ” Id. (internal quotation marks and citation omitted). This court in Newegg considered and rejected Soverain’s arguments about the prod uct identifier. We discussed the testimony by Soverain’s expert that the CompuServe system lacked the product identifi er limitation and rejected the expert’s conclusions. Newegg , 705 F.3d at 1339

– 40. We found that “[t]he pro duct identifier message term does not distinguish the shopping cart claims from the prior art CompuServe Mall .” Id. at 1340.

Soverain also argues that it did not have the oppo rtunity in Newegg to present its arguments that the co nfirmation numbers from the CompuServe Mall system did

n ot satisfy the limitations of th e hypertext statement claims (c laims 15 and 39 of the ’492 patent)

. Soverain argues that its expert testimony estab lished that the CompuServe system did not provide online access to information or suggest providing hyperlin ked transaction documents , as required by the claims

. But Soverain made this same argument in its Newegg briefing , stating that “[t]he CompuServe Mall did not have the capability for customers to review their order status or transaction history online.” Br ief of Plaintiff

- Appe llee Soverain Software LLC at 46

, Newegg , 705 F.3d 1333 (No. 2011

- 1009)

. In Newegg , we addressed Soverain’s argument that

, in the “CompuS erve Mall [,] it might be necessary to resort to theSOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 14

telephone or email to get the transaction info rmation . . . . ” 705 F.3d at 1343. We reasoned that the patentee “did not invent the Internet, or hypertext, or the URL.

. . . [T] he use of hypertext to communicate ‘a stat ement document’ or ‘transaction detail document’ was a routine incorporation of Internet technology into existing processes.” Id. at 1344 (citations omitted).
Soverain further argues that it did not focus on the credibility of Newegg’s expert witness “because Soverain was seeking to affirm JMOL of non

- obviousness by rel ying on [Newegg’s expert’s] failure to establish that certain claim elements were prima facie present.” Appellee ’s Br. 29

. Specifically , Soverain argues that it would have present ed evidence that Newegg’ s expert, Mr. Tittel, was discredited on cross

- examination because he a dmitted that he did not conduct an element

- by

- element compar ison of the claims to the prior art, apply the district court’s claim construction, or review the prosecution history of the patents

. But Soverain did have the incentive to raise these arguments in the Newegg appeal. The district court had issued JMOL for Soverain, having found that Newegg failed to present a prima facie case of obviousness. Newegg , 705 F.3d at 1337. On appeal, the question was whether JMOL was inappropriate because Tittel’s test imony established a prima facie case of obviousness, as Newegg argued. See id. We concluded that Tittel’s test imony established that each element of the claims was present in the CompuServe system and relied on that testimony

. Id. at 1338, 1342

– 43. Soverain did have the incentive to argue that Tittel’s testimony did not support Newegg’s obviousness arguments because Mr. Tittel , for example, did not conduct an element

- by

- element analysis

. The fact that Soverain had arguments which it did not make does not mean that Soverain lacked the incentive to make them.SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 15

II

The remaining question is whether issue preclusion applies to invalidate claim 39 (a hypertext statement claim) of the ’492 patent

. Claim 39 depends from claim 15. Claim 15 was invalidated as obvious in Newegg

. See Newegg , 705 F.3d at 1344 (invalidating as obvious claim 41, which depends from claim 15)

. The only additional limit ation in claim 39 concerns the I nternet. Claim 39 recites “[a] hypertext statement in accordance with c laim 15, 7 wherein the network is an Internet. ” ’492 patent Reexamination Certificate C1 col. 1 ll. 21

– 22.

Soverain argues that issue preclusion should not a pply because claim 39 was not previously found obvious and does not present identical issues

. Compl ete identity of claims is not required to satisfy the identity -of- issues requirement for claim preclusion

. Ohio Willow Wood , 735 F.3d at 1342 ; see Aspex , 672 F.3d at 1341 (in the claim preclusion context). “If the differences between the una djudicated pate nt claims and adjudicated patent claims do not materially alter the question of invalidity, collateral estoppel applies.” Ohio Wi llow Wood , 735 F.3d at 1342 (citing Bourns, Inc. v. United States , 537 F.2d 486, 493 (Ct. Cl. 1976)). In Ohio Willow Wood

, we applied issue preclusion to invalidate a claim where a different claim in another patent had previously been invalidated because “the[] patents use[d] slightly different language to d escribe substantially the same invention.” Id. We also found that a diffe rence in claim scope was not fatal to the application of estoppel. Id. at 1343. The previously

invalidated claim contained a limitation requiring only polymeric gel, whereas the unadjudicated claim required, more specifi cally, block copolymer gel. Id. We h eld that, because the patentee failed to explain how the additional limitation would change an invalidity analysis, the p a7 The language of claim 15 is quoted, supra , n.2.SOVERAIN SOFTWARE LL C v. VICTORIA ' S SECRET 16

tentee had not met its burden in opposing summary judgment. Id.

The additional limitation here

— transmitting a hype rtext statement over the Internet, rather than over a generic network

— does not materially alter the question of the validity of claim 39

. In Newegg , as to the hypertext statement claims, the court noted that Newegg’s expert Tittel had testified that CompuServe was not on the Internet. Newegg , 705 F.3d at 1343. We explained that , as conceded by Soverain’s expert Shamos, t he patentee “did not invent the Internet, or hypertext, or the URL. ” Id. at 1344 (citing Shamos testimony) . “ [T] he use of hypertext to [perform the limitations of the hypertext statement claims] was a routine incorporation of Internet technology into existing processes. ” Id. (citations omitted)

. Here, too, the routine incorporation of Internet technology in claim 39 does not change the invalidity anal ysis.
The invalidity of the asserted claims of the ’314 and ’492 patents is established by issue preclusion. The judgment of infringement and no invalidity accordingly is reversed.
