Hello Everyone,
I will be discussing the anticipation, obviousness, and validity of various sleeve patents described in the previous post.
Patent US 6,343,735 B1, titled Insulating
Sleeve, was issued on February 5, 2002 and filed on May 4, 2000. Validity, non-obviousness, and anticipation
comes from switching from standard Styrofoam containers to paperboard sleeves with
a top corner where the user would not directly have to touch the walls of the
cup. As I find this corner useful when securing drinks, I find it a novel idea.
Delbert E Phinney’s Patent 2661889, Thermal
Coffee Cup was filed on July 20, 1946 and issued December 8th, 1953. -
From the first filing date and issue, we can see
that this patent took 7 years to be issued. Anticipation, validity, and non-obviousness
comes from providing a cover cap for a coffee cup where a portion can be torn
away to permit drinking, without removal of the entire cup. This promotes longevity
of warmth in the drink.
John E. Katchko and David Uitenbroek’s Patent US
8251277 titled Thermal sleeve, method for manufacturing a thermal sleeve, and
combination cup and thermal sleeve has a priority date of April 15, 2005 and
published August 28, 2012. -
The main purpose claims that this sleeve can not
only be used for hot beverages, but cold ones as well. Along with a creeped paper inside to provide thermal insulation this is what provides for the
anticipation, validity, and non-obviousness.
Kevin Prince’s US7922031 Patent titled Insulator
sleeve for a beverage container has a priority date of March 1, 2006, and was
published April 12, 2001.This sleeve allows for the maker to make
customizations of the sleeve with different layers, colors, and writing
abilities. This is where the anticipation, validity, and
non-obviousness comes from. I do not find this to be much a novel idea, and more of a copy from previous inventions.
Wendy and Donald LaGuardia’s US 8118189 titled
Temperature-indicating sleeve and related container has a priority date of June
19, 2008 and was published February 21, 2012. Anticipation, validity, and non-obviousness come
about through the temperature-indicating diagrams on the sleeve that also
provides insulation. This way the consumer knows how hot the drink is.
James Rule’s US 6152363 patent titled Sleeve
construction for improved paperboard cup insulation has a priority date of May
3, 1999 and publication date of November 28, 2000. -
The new design of possibly removing the hot-melt
glue dots for syntactic foam is stated to create easier assembly while
maintaining insulation and customization properties. This validates
anticipation, validity, and non-obviousness. I can see how this could be considered new and different, but I do not find it to be a very novel invention.
Andrew Spriegal and Howard Loewanthal’s Patent
US20078824. The new layer of elastomer in addition to the
three types of conical sleeve such as silicon, rubber, and butyle provide for
anticipation, validity, and non-obviousness.
Barry Silverstein, Matthew Cook, James Hubbard,
and Kurt Wolf’s 20100019023 patent. The edges with peaks, assembly method, and accessibility
with at least two fingers and a thumb provide validity, non-obviousness, and
anticipation as it a reinvented design for maximized comfort.
Eugene Chun’s 20140151385 Patent titled Hot and
Cold Cup Sleeve. Anticipation, validity, and non-obviousness are
supported by the three layered design, where the inner layer is water
absorbent, while the outer layer keeps the hand dry and safe from burn.
