need not decide that issue because the firm has not appealed. See Corroon v. Reeve, 258 F.3d 86, 91 (2d Cir.2001) ("[B]ecause more than one entity was sanctioned, [the sanctioned law firm] surely could not be viewed as an appellant, for it is not ‘a party whose intent to appeal is otherwise clear from the notice.’ ” (quoting Fed. R.App. P. 3(c)(4))). Similar to Corroon, the notice of appeal in this case states only that "Notice is hereby given that Plaintiff, DTND ... hereby appeals.” Compare Finlay v. Olive, 77 S.W.3d 520, 527 (Tex. App. — Houston [1st Dist.] 2002, no pet.) ("[A] law firm may be sanctioned for groundless pleadings filed on its behalf by an attorney employed with the firm.”), with Yuen v. Gerson, 342 S.W.3d 824, 828-29 (Tex.App.— Houston [14th Dist.] 2011, pet. denied) (<HOLDING>). Likewise, we do not address DTND’s argument
holding that defenses under rule 60b may be waived holding that it may not holding that it may be decided as a matter of law holding that case law interpreting rule 11 may be use to interpret rule 9011 holding that a law firm may not be sanctioned under rule 13 or  10004
