US 6,343,735 B1 - The Insulating Sleeve:
- The validity of this patent can be upheld as this is an invention that it quite novel. Traditionally, foam cups had been utilized to protect consumers from the heat emitted by a cup so this idea can be considered non-obvious as it differentiates itself from the foam cup and traditional sleeve.
US 2,661,889 A – Thermal Coffee Cup:
- The validity of this patent can be upheld as this invention, when it was created in the 1940s, was completely new as there had not existed an invention that had been patented before to carry hot beverages. Due to its widespread use, non-obvious nature, and lack of prior art at the time, this patent had substantially strong validity.
US 8,251,277 B2 – Thermal Sleeve, Method
for Manufacturing a Thermal Sleeve, and Combination Cup and Thermal Sleeve:
- The validity of this patent is not as strong due to the obvious nature of the entire invention. It simply expands on the thermal, insulating sleeve patented earlier so its close relation to the prior art makes it simple to anticipate its purpose and use.
US 7,922,031 B1 – Insulator Sleeve for a
Beverage Container:
- The obviousness of the patent weakens the validity of this as it simply allows for the sleeve to be reusable. Its lack of differentiation makes it prone to becoming invalidated in light of evidence suggesting its obviousness and lack of invention.
US 8,118,189 B2 – Temperature-Indicating
Sleeve and Related Container:
- The validity of this patent is very strong due to the fact that it introduces the new technology of allowing consumers to know the temperature of their beverage. Due to its novelty, the non-obvious nature of this patent allows for the enforceability of this patent.
US 6,152,363 A - Sleeve Construction for
Improved Paperboard Cup Insulation:
- Due to the new technology of hot-melt glue dots, the validity of this patent can be established as it incorporates a new solution for thermal insulation. The non-obvious factor established by this technology is what maintains the validity of the patent.
US 20080078824 A1 – Beverage Cup
Sleeving System and Method:
- The ability for users to insulate both hot and cold beverages was a new technology that makes this patent quite non-obvious. Due to its non-obvious nature and novelty, the validity of this patent is upheld as the argument behind the extra features that this technology incorporates is its primary defense.
US 20100019023 A1 – Protective Sleeve:
- While the overall technology is rather standard and is not relatively new, the “arch” design is the feature that makes this patent quite novel. Due to the overall change in design, the validity of this patent can be defended, as the prior art did not possess such a feature.
US 20140151385 A1 – Hot and Cold Cup
Sleeve:
- The sleeve for hot and cold beverages was a relatively new technology making its validity quite strong due to its novelty and non-obvious nature.
Great overview of each patent. I agree with your insights, I will definitely check your blog more in the future.
ReplyDeleteHi Rushil,
ReplyDeleteI liked how detailed this was in relating anticipation and obviousness to all of the patents. I could clearly see your analysis regarding these two requirements for each of the patents. One tip for next time is to maybe incorporate some diagrams of the patents so that we can better remember the details about it.
Jessica makes a great point. Though you did a great job in outlining all of the patents, pictures and diagrams could have been really beneficial. Combining your concise descriptions with visual aides could only make your posts better. Great work!
ReplyDeleteI really like how you discussed each patent by patent the same way you went over their claims.
