Tennessee Chill Box’s heat-beating air conditioned
respirator system is published in U.S. patent application
After an 18-month wait, the United States Patent and Trademark Office (USPTO) has officially published Tennessee Chill Box’s utility patent application.
The company’s patent journey began on November 23, 2010, when it filed a
provisional application with the USPTO. A provisional application is basically
an early filing date for a patent application, contingent upon the subsequent
filing of a full-fledge utility or design patent application.
“You have one year to apply for a utility patent and we applied for that last
November,” said Mike Asbra, owner of Tennessee Chill Box. “They published it
on May 24th.”
The USPTO maintains an application’s confidentiality for 18 months after the
earliest application filing. In this case, the provisional application filing date
was included in that timeframe. After 18 months, the patent application is
published and publicly available.
Tennessee Chill Box’s application, “Air Conditioned and Heated Ambient
Fresh Air Supply System,” is now hosted on the USPTO’s website. Asbra,
who has experience with drafting, drew
all of the diagrams himself. Even
still, hiring a patent attorney was
crucial in conducting the patent
search and making claims.
“I had to really cover my
bases,” said Asbra. “My patent
covers everything from a
fresh air supply system that’s
air conditioned from a blower
Asbra’s objective in applying for a patent
is to protect the company’s blower-driven air
conditioned air supply system, the Chill Box
8000. While he formulated the idea for the Chill
Box in the early 2000’s, it took Asbra several
years to achieve a final design where fresh air
was cooled in a consistent manner.
