What this record means
The record shows that the mark “MASTERCHECK” is no longer active; it was cancelled on May 04 2012 because the registrant, Abbott Laboratories, did not file a required declaration. The mark had been registered on the Principal Register in 2001 for chemical controls used with diagnostic instruments and reagents for scientific use. A similar name would raise the closest concern in that same narrow field of laboratory chemicals and reagents. The record does not give Abbott control over every use of the wording, only over the specific goods listed. The prosecution history shows the mark was initially allowed on the Principal Register, then later cancelled under Section 8, with no indication that it ever moved to the Supplemental Register. No opposition, cancellation, or court action appears in the supplied history, so there is no visible enforcement activity. For someone looking to use a similar name, the cancelled status means the mark is not currently enforceable, but the specific goods listed still represent a potential area of concern.
