OPINION OF THE COURT
Thе main issue presented by this appeal is whether a New York law firm retained to defend a corporate client in a Florida patent infringement litigation had a duty to advise the cliеnt about possible insurance coverage for the costs of the litigation. Under these facts, we conclude that it did not.
Background
Defendant VSI is a Florida corporation that sells nonprеscription reading glasses to retail chain stores. In December 1990, defendant Myron Orlinsky, VSI’s Chief Executive Officer, retained plaintiff law firm to represent VSI in two Florida lawsuits alleging patent, trademark and trade dress infringement based on VSI’s design of “hanger tags” used to display reading glasses
(see, Al-Site Corp. v VSI Intl.,
42 USPQ2d [BNA] 1876 [US Dist Ct, SD Fla],
affd in part, revd in part
On December 3, 1997, defendants answered the complaint and asserted counterclaims, alleging legal malpractice and breach of fiduciary duty based on plaintiffs failure to advise them of possible coverage for their litigation expenses under their then-existing general liability insurance policy. Defendants noted that, unlike plaintiff, successor counsel successfully secured coverage for their litigation expenses under said policy in 1994. 1 However, defendants’ carrier denied coverage for any costs incurred during plaintiffs representation of defendants.
*312 Plaintiff subsequently moved for summary judgment agаinst VSI on its cause of action for an account stated, and for dismissal of defendants’ counterclaims for failure to state a cause of action (CPLR 3211 [a] [7]). Defendants oppоsed the motion and cross-moved to amend their answer to include an additional counterclaim for breach of contract. This time, defendants alleged that, prior to the Florida litigation, plaintiff misadvised them on the potential liability arising from their marketing and use of “hanger tags.”
Supreme Court denied plaintiff’s motions for summary judgment and for dismissal of defendants’ counterclaims, and, upon reargument, granted plaintiff’s motion to dismiss defendants’ newly asserted counterclaim as time-barred. In denying plaintiff’s motion to dismiss, the court concluded that plaintiff’s failure to investigаte defendants’ insurance coverage presented an issue of fact as to the scope of plaintiff’s engagement. The court found it “particularly noteworthy that counsеl which succeeded the plaintiff promptly pursued the insurance issue to the defendants’ substantial benefit” (
The Appellate Division modified by awarding plaintiff summary judgment on its account stated claim and dismissing defendants’ counterclaims for failure to state a cause of action. The Court held that, absent a factual allegation that plaintiff’s representation specifically encompassed advice on insurance coverage, plaintiff owed defendants no duty to inquire into the nature and scope of that coverage. The Appellate Division certified the following question to us: “Was the order of this Court, which modified the orders of the Supreme Court, properly made?” We answer that question in the affirmative.
Analysis
The gravamen of defendants’ legal malpractice claim is that plaintiff had a duty to advise them that their general liability insurance policy might cover Florida litigation costs. Defendаnts’ claim is based on a then novel theory that patent insurance coverage was available under an “advertising liability” clause in general liability policies
(see, e.g., Intex Plastiсs Sales Co. v United Natl. Ins. Co.,
18 USPQ2d [BNA] 1567 [US Dist Ct, CD Cal],
revd
To sustain a cause of action for legal malpractice, a party must show that an attorney failed to exercise “the ordinary reasonable skill and knowledge” commonly possessed by a member of the legal profession
(Byrnes v Palmer,
At the time of plaintiff’s representation, neither New York nor Florida recognized the duty of an insurer to defend patent infringement claims under a general liability policy’s advertising injury clause. To the contrary, both States had rejected coverage for similar claims
(see, Meyers & Sons Corp. v Zurich Am. Ins. Group,
*314
Moreover, the theory of such coverage remained largely undeveloped at the time of plaintiffs representation, with only a handful of courts, particularly in California, finding а duty to defend patent infringement claims
(see, e.g., John Deere Ins. Co. v Shamrock Indus.,
Despite the contrary case law, defendants urge us to recognize a duty based on out-of-State cases which have broadly cоnstrued an advertising liability clause to encompass patent infringement claims. Many of the cases relied upon, however, post-date plaintiffs representation of defendаnts, and none specifically address the issue before us. 2
Although defendants acknowledge the novel nature of their claim, they maintain that, as a highly specialized patent law firm, plаintiff had a duty to keep abreast of emerging legal trends. We agree that attorneys should familiarize themselves with current legal developments so that they can make informed judgments аnd effectively counsel their clients
(see,
Code of Professional Responsibility EC 6-2). However, plaintiff in this case should not be held liable for failing to advise defendants about a novel and questiоnable theory pertaining to their insurance coverage
(see, MCEG Sterling v Phillips
*315
Nizer Benjamin Krim & Ballon,
Defendants’ remaining contentions are without merit. The Appellate Division proрerly granted plaintiffs motion for summary judgment on its cause of action for an account stated. Defendant Orlinsky’s self-serving, bald allegations of oral protests were insufficient to raise а triable issue of fact as to the existence of an account stated
(see, Zuckerman v City of New York,
Accordingly, the order of the Appellate Division should be affirmed, with costs, and the certified question answered in the affirmative.
Chief Judge Kaye and Judges Levine, Wesley and Rosenblatt concur; Judge Smith taking no part.
Order affirmed, etc.
