In this concurrent use proceeding, the United States Patent and Trademark Office (PTO) Trademark Trial and Appeal Board (board) granted summary judgment in favor of Labor Force, Inc. (Labor), holding that, as a matter of law, Action Temporary Services, Inc. (Action), was not a concurrent lawful user of the service mark LABOR FORCE within the meaning of section 2(d) of the Lanham Act.1 We reverse that judgment and remand this case to the board for further proceedings.
Issue
The principal issue on appeal is whether a federal registration of a mark in force at the time of an applicant’s adoption of the same or similar mark, which federal registration subsequently is canceled, prevents, as a matter of law, the applicant from being a “lawful use[r]” of its mark, within the meaning of section 2(d) of the Lanham Act, subsequent to that cancellation.
Background
Although many of the facts are disputed, the following facts are not contested. On June 13, 1973, Labor filed a service mark application on the mark LABOR FORCE for its service of supplying temporary help to others. On July 1, 1975, Labor’s mark was granted federal registration No. 1,014,-980 on the principal register.
On August 1, 1975, Action adopted the mark LABOR FORCE for its service of supplying temporary help to others. Action’s adoption of its mark was subsequent in time to Labor’s receipt of its federal registration.
In 1981, 6 years after Labor obtained its federal registration, that registration was canceled by the PTO on the basis of Labor’s failure to file an affidavit of continuing use under section 8 of the Lanham Act.2 Since that time, there have been no subsequent federal registrations for the mark.
*1565On July 21, 1982, Labor filed application No. 375,781 (’781 application), to register on the principal register the service mark LABOR FORCE for supplying temporary help to others. Labor recited a first use date of May 1970.
On February 2,1984, Action filed application No. 463,700 to register on the principal register its mark LABOR FORCE for supplying temporary help to others. Action claimed first use as of August 1975. The PTO suspended Action’s application pending disposition of Labor’s earlier filed ’781 application.
Upon publication of Labor’s mark in the PTO’s Official Gazette, Action timely filed an opposition against registration of that mark. Subsequently, Action amended its application to one for concurrent use, naming Labor’s use of the mark in Texas and Tennessee as an exception to Action’s exclusive right to use the mark. The PTO dismissed Action’s opposition and a concurrent use proceeding was instituted.
The board granted summary judgment to Labor, holding that Action was not a lawful concurrent user. In reaching its disposition, the board held that, as a matter of law, Action was not a concurrent lawful user of the mark because its adoption on August 1, 1975, of the mark LABOR FORCE was not in good faith. The board concluded that “having been put on notice of Labor’s use in 1975, Action cannot claim that its continued use in 1981 was without knowledge of Labor’s use.”
For the reasons set forth below, we hold that the board erred, as a matter of law, by entering summary judgment in this case.
Analysis
In reviewing whether the board correctly entered summary judgment in favor of Labor, we apply the same legal standard as that applied by the board in determining whether summary judgment was appropriate.3 Summary judgment may be granted only when the pleadings and evidence of record “show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” 4
At the threshold of concurrent use registration, as provided for by section 2(d) of the Lanham Act,5 is “lawful use.” “A valid application cannot be filed at all for registration of a mark without ‘lawful use in commerce,’ and, where a claim is made of concurrent rights, such use must begin prior to the filing date of any application by a conflicting claimant to the mark.” 6
Here, subsequent to the cancellation of Labor’s federal registration in 1981, and prior to Labor’s filing of its application on July 21, 1982, there were no applications pending, or federal registrations existing, on the service mark LABOR FORCE. During that period, both Action and Labor allege use of their respective marks, the former having alleged use from August 1975 and the latter having alleged use from May 1970. Action’s use between 1981 and July 21, 1982, was prior to the filing date of Labor’s application. In view of these allegations, the board, however, concluded that Action adopted its mark on August 1,1975, with constructive notice of Labor’s use of the same mark and that the existence at that time of constructive notice of Labor’s *1566mark prevented Action, as a matter of law, from being a lawful user of the mark subsequent to the cancellation of Labor’s registration. We cannot agree.
It is well established that, pursuant to section 22 of the Lanham Act,7 a registration provides constructive notice for all use during the existence of the registration.8 However, a canceled registration does not provide constructive notice of anything.9 A canceled registration cannot prevent a party from being a “lawful user” of a mark when that party’s use is subsequent to the cancellation of the federal registration.
The board’s reasoning, that “[w]hat had been an unlawful adoption when it occurred was still unlawful,” i.e., that because Action’s adoption of its mark was “unlawful,” Action cannot claim that its use of the mark after Labor’s registration was canceled may be lawful, is flawed. Whereas actual notice, once obtained by a party of another party’s use of a mark, exists independent of the event giving' rise to that notice, constructive notice, pursuant to section 22 of the Lanham Act, exists, and lasts, only as long as the federal registration giving rise to that constructive notice remains in effect. Here, in view of the existence of Labor’s federal registration, Action’s use of its mark during the penden-cy of Labor’s federal registration cannot be deemed “lawful use.” Nevertheless, Action’s use following the cancellation of Labor’s federal registration was not subject to any former constructive notice effects of that registration.
On remand, the board shall determine the relative rights of the parties based on our holding that the constructive notice effects of Labor’s federal registration prevented Action from being a lawful user only during the existence of that registration. The board shall consider the effects of actual notice, which must “always be the product of the particular fact pattern involved in each case,” 10 bearing in mind the holding of one of our predecessor courts that “mere knowledge of the existence of the prior user should not, by itself, constitute bad faith.” 11
Conclusion
For the reasons discussed, the board’s grant of summary judgment in favor of Labor on grounds that Action could not be a lawful concurrent user is reversed. Because the board’s decision rested exclusively on its erroneous legal conclusion that the constructive notice effects of Labor’s canceled federal registration precluded Action from being a lawful user of its mark subsequent to that cancellation and did not reach any other issues underlying concurrent use, we remand this case to the board for further proceedings.
