Problem

We request previously undiscovered prior art including products in use, patents and non-patent literature (for example advertisements, technical descriptions, etc.) in English and foreign languages that can help invalidate claims 9-11 of US patent 6,920,645 (‘645) - “Apparatus and method for making an ear warmer and an ear warmer frame” and claims 14-20 of US patent 6,735,784 (‘784) - “Apparatus and method for making an ear warmer and an ear warmer frame.”

These patents describe ear warmers formed by enclosing a solid frame between two pieces of membrane material, both with the approximate shape shown in the figures below.

If you are new, see patent and prior art basics and tips for Patexia's prior art contests, and refer to the submission notes below. The prize is guaranteed to be paid if we receive a qualifying submission. The following questions will help you understand what we are looking for in this study.

 

Fig. 1: [Fig. 28 from 645 patent]

 

 

Fig. 2: [Fig. 29 from 645 patent]

 



 

 

 

Fig. 3: [Fig. 10 from 784 patent]

 

 

Fig. 4: [Fig. 21 from 784 patent]

 

Questions

 

The reference(s) should clearly satisfy the following:

For claims 9-11 of the ‘645 patent and claims 14 – 21 of the ‘784 patent:

  1. Was it published before April 5th, 1999 (clearly dated)?
  2. Does it show ear warmers shaped approximately like either of those in Fig. 1?
  3. Does the ear warmer have a shell?
  4. Is there a solid frame inside the shell?
  5. Is the frame single-piece (unitary)?
  6. Does the frame have an ear portion that defines an opening?
  7. Is the width of the middle portion smaller than the width of the ear portions (as in Fig. 1)?
  8. Is the frame inside the ear portion substantially circular?
  9. Is the frame approximately shaped like that in Fig. 3?
  10. Is the outer shell made by attaching (sewn/glued) the edges of two flat pieces of material shaped like Fig. 1?

Contest entries can alternatively include a combination of several references from which the above ear warmers are obviously made.
