Seems that it did. On IMDB the writers credits are;-
'Alfredo Salazar Bob Kane Bill Finger'
First of Kane and Finger are listed as uncredited, so their names aren't on the movie.
Second IMDB is not the most reliable source. A few years ago they gave the Alfred in the movie serials the last name Pennyworth, despite that name not being invented until the 1960s. Currently they use the last name Beagle which wasn't created until the 1950's and, I believe was used twice, once in the comic books, & once in the comic strip.
I think some fan just added the Kane & Finger attribution since they are both considered to be Batman's creators, although that wasn't the case until just a few years ago. So if DC had complained only Kane would have gotten a credit, which, as pointed out, wasn't on the movie.
Most likely this Mexican movie just floated under DC's radar. Also DC hadn't used Batwoman for around 6 years, so they may not have considered it important enough to make a fuss about.
Hmm! Is that the inspiration for DC's character Blue Devil?
Probably not. More likely they named it after the college mascot for Duke University.
Heck Marvel had good luck using the mascot for the University of Michigan. ;-)
