:::They also have nothing to do with the honourable Mr. Parham, so do please leave him out of this.:::

sure it does. If you can reverse engineer and copy my designs why couldn't you do the same with Mr. Parham's designs?

Please explain the material differences btwn our cases?

or is the only difference that you have not yet targeted mr. Parham for pirating of his designs?

Doug further states;

:::...it is long since entered the public domain.:::

exactly when (what date) did the Peerless designs enter the "public domain"? Was it a willing gift to the public by the owner of Peerless at that time? Did they announce that they had abandoned their interests in their own designs?

Doug writes further that;

:::The design is accessable by any person wishing to discover it.:::

like I said... so, as an example, Wayne's speaker designs are fair game for you or anyone else to reverse engineer and copy and offer for sale... in direct competition to Mr. Parham so long as he does not have patent protection?

I guess any product with a lid that not welded securely in place is fair game.
