PER CURIAM: ^[*]

Stephen M. Avdeef appeals the summary judgment dismissal of his copyright infringement complaint against Google, Inc. While pro se briefs are afforded liberal construction, even pro se litigants must brief arguments in order to preserve them. Yohey v. Collins , 985 F.2d 222, 224-25 (5th Cir. 1993). Avdeef fails to set forth the substance of his claims in meaningful detail and does not address the grounds upon which the district court dismissed his *2 Case: 15-10946 Document: 00513896444 Page: 2 Date Filed: 03/03/2017

No. 15-10946

complaint. He does not mention the district court’s finding that Google was entitled to protection under the safe harbor provision of the Digital Millennium Copyright Act, 17 U.S.C. § 512. By failing to challenge the district court’s reasons for granting summary judgment in favor of Google, Avdeef has abandoned the claim on appeal. See Brinkmann v. Dallas County Deputy Sheriff Abner , 813 F.2d 744, 748 (5th Cir. 1987).

In his complaint, Avdeef also named Google’s chief legal officer, David C. Drummond, as a defendant. In a final appealable order, the district court dismissed Avdeef’s complaint against Drummond for lack of personal jurisdiction. See F ED . R. C IV . P. 54(b). Because Avdeef failed to file a timely notice of appeal as to this order, we lack jurisdiction to consider any claim challenging the dismissal of Drummond as a defendant in the instant action. See F ED . R. A PP . P. 4(a)(1); Bowles v. Russell , 551 U.S. 205, 214 (2007).

AFFIRMED IN PART; DISMISSED IN PART FOR LACK OF JURISDICTION.
