Honda Estate vs. Toho Ramifications?

Above, yours truly with the Godzilla statue at Toho Studios.

The story of the alleged copyright lawsuit against Toho by the heirs of Ishiro Honda over the Godzilla character may have some big ramifications if 1.) the story is true or, 2.), they actually win.

The story does not sound Japanese to me. Maybe in America, perhaps (i.e., Bela Lugosi Jr.'s legal actions over his father's image and The Three Stooges).

If the story is true and Honda's heirs prevail and win the Godzilla copyright from Toho, could we see Noriaki Yuasa's estate taking similar action against Kadokawa Pictures (the successor company to Daiei) over the Showa Gamera and Shusuke Kaneko over the Heisei Gamera? Who knows what (or who) may come out of the woodwork?

It will be interesting to see how this plays out, if true.
