At risk of being repetitive, the person who was granted the patent made NO CLAIM on the basic idea of a screened bottom board, and clearly acknowledged the developments prior to the patent application. All that was patented was a screened bottom board with SPECIFIC FEATURES. Those specific features, as applied to a screened bottom board are really all that was "patented". It seems unfair to accuse someone of "seeking credit" when they did a more than adequate job (as is required in any patent application) of giving credit where credit is due, at least to prior patents.
