Ever wondered what all went into that coffee sleeve that allows you to hold your warm cup of mocha without burning your hands? Let's take a walk down the patent road, entailing some of the oldest to the newest applications for coffee lids, sleeves, and more!
ISSUED PATENTS
Publication type: Grant
- US 6343735 B1 Insulating sleeve
Priority date: May 4, 2000
Publication date: Feb 5, 2002
Background: Cups changed from insulated Styrofoam to an alternative material that is inexpensive, biodegradable, and has insulating properties to protect that user's hand from the temperature of a liquid in the cup.
Claim: "An insulating container holder for a container having a sidewall, said holder comprising a sleeve having a top opening and a bottom opening and a passageway between said top opening and said bottom opening for receiving the container, said sleeve conforming to the container sidewall over a first portion of the surface area of the sidewall, said sleeve including first and second sleeve portions angled away from the sidewall and separated therefrom by a spacer to form a gap between said at least one sleeve portion and the sidewall and said first and second sleeve portions extending between said top opening and said bottom opening." The insulating sleeve will be a holder that will be placed on top of the mug in order to protect the user's hand

Publication type: Grant
Priority date: July 20, 1948
Publication date: Dec 8, 1953
Background: For use in a coffee cup which requires simple construction, is inexpensive to manufacture, easy to assemble, of high convenience, and efficient in operation
Claim: A coffee cup cover which will have a a hole in which the user can drink from with still have the rest of the lid covered
This has allowed for sipping on coffee

Publication type: Grant
Priority date: April 15, 2005
Publication date: August 28, 2012
Background: In relation to cup sleeves
Claim: This patent provides a specific type of a cup sleeve, namely a thermal sleeve. It also explains the specific method that would be used - a creped paper product wit a first and second ending, and a first and second cup opening. Specific dimensions are provided.
Specifically, the creped paper has about 8 to 100 crepe lines per linear inch and a basis weight (prior to creping) of about 20 lbs/3000 ft2 to about 150 lbs/3000ft2 according to TAPPI T410
Publication type: Grant
- US 7,922,031 B1 Insulator Sleeve for a Beverage Container
Priority date: March 1, 2006
Publication date: April 12, 2011
Background: This patent further develops on the first patent, which provided for an insulating sleeve, but which had only been made as a disposable sleeve. If a consumer attempts to reuse those past sleeves, they usually look worn out or get damaged after repeated uses. Thus, one main advantage of this item is the environmental benefits since the sleeve will be non-disposable.
Claim: An insulating sleeve with a frusto-conical beverage cup (one which is given out by coffee shops) with an opaque inner sleeve and an outer sleeve such that both sleeves are coaxially aligned.

Publication type: Grant
- US 8118189 B1 Temperature-indicating sleeve and related container
Priority date: Dec 15, 2006
Publication date: Feb 21, 2012
Background: Since insulated sleeves are used, the consumer of the purchased beverage may not know the current temperature of the liquid in the cup.
Claim: A non-disposable, thermally insulated container with a sleeve which has a temperature indicator affixed to the sleeve. It will be affixed at a visually observable location.

The hot-melt glue dots design
- US 6152363 Sleeve construction for improved paperboard cup insulation
Priority date: May 3, 1999
Publication date: Nov 28, 2000
Background: This involves the construction of sleeves for use with paperboard cups
Claim: The construction uses hot-melt glue dots for improved insulation of a paperboard cup so it can be to the same level as common polystyrene cups.
PATENT APPLICATIONS
- US 20080078824 A1 Beverage cup sleeving system and method
Publication type: Application
Priority date: August 23, 2006
Publication date: April 3, 2008
Background: This is an improvement of the current cup sleeve patents which will be effective when the sleeve is wetted, effective against extremely high and low temperatures, is reusable, and easily manufactured.
Claim: This cup insulating system has a layer of elastomer formed into a homogenous seamless conical sleeve.
- US 20100019023 A1 Protective sleeve
Priority date: July 25, 2008
Publication date: Jan 28, 2010
Background: Sleeves are needed to allow for comfortable and convenient control of very hot or cold foods.
Claim: A sleeve with a blank with a first and second edge, specifically with the first edge having at least one peak with regard to the second edge, as the figure shows.
- US 20140151385 A1 Hot and Cold Cup Sleeve
Publication type: Application
Priority date: Feb 6, 2014
Publication date: June 5, 2014
Background: This patent has to do with disposable sleeves in the realm of handling very hot or cold beverages.
Claim: A disposable sleeve with the following features: a water-absorbent lining, a water-repellent outer layer, a polyethylene coating laminate film layer as an adhesive to bind this lining to the outer layer. The inner and outer layers are adhered together with an invisible (post-fabrication) polyethylene film.
The following diagram gives some insight on the water-absorption feature of the sleeve:
ANTICIPATION AND OBVIOUSNESS:
I really don't think any of these inventions were at all obvious! Each patent has a clear and unique functionality which makes the new addition to the cup sleeve or lid a very feasible idea. Accordingly, I claim that all these patents have required novel thought, and thus - are not anticipated.
A Deeper look on anticipation & obviousness (+3 unit student)
This claim is based off of the prior art of the cup sleeves. So for example, going from the first patent described of a simple cup sleeve - there is a lot of novel thought which has gone into creating a sleeve that then allows for functionalities such as an indication of temperature or better liquid absorption.
This is basically how ideas evolve and get better over time. The first patent (US 6343735 B1 Insulating Sleeve) provided for the general idea and helped create an environment-friendly option for coffee cups. Another patent (US 8118189 B1 Temperature-indicating sleeve and related container) took a complete different approach on this already established invention. Instead of simply changing the color of the sleeve (an issue of obviousness) or adding designs to the sleeve (an issue of anticipation), this patent allowed the user of the container to know the temperature of the liquid in the container. In the background section of the patent, the author of the patent relates this to the coffee industry where it would be very beneficial for consumers to know if their coffee is very hot or too cold.
