body: On the United States Patent and Trademark Office the [Trademark Electronic Search System (TESS) has an entry for "SQL Server" that says](http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4807:go6ru4.2.3)
  
  
  
  > 
  > **Word Mark** SQL SERVER
  > 
  > 
  > 
  
  
  And, then
  
  
  
  > 
  > **Trademark Search Facility Classification Code** `LETTER-3-OR-MORE` SQL Combination of three or more letters as part of the mark

  How do I read that, does that mean the term `SQL` is Trademarked by Microsoft? Other queries for example ["SQL Boost"](http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4807:go6ru4.3.37) **and** ["SQL Sonic"](http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4807:go6ru4.5.18) make no mention of SQL and explicitly say,
  
  
  
  > 
  > NO CLAIM IS MADE TO THE EXCLUSIVE RIGHT TO USE "SQL" APART FROM THE MARK AS SHOWN
  > 
  > 
  > 
  
  
  [Others examples say](http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4807:go6ru4.5.3),
  
  
  
  > 
  > NO CLAIM IS MADE TO THE EXCLUSIVE RIGHT TO USE "SQL" APART FROM THE MARK AS SHOWN
  > 
  > 
  > 
  
  
  Going off this, should I assume Microsoft is making a claim at "SQL"?
