An Ohio man who accepted an approximately $100,000 settlement for his Vioxx personal-injury claim has filed a negligence suit against three Houston firms and three Houston lawyers, alleging the defendants made paperwork errors in his case file that reduced the size of his settlement.

Craig Pingle, who lives in Hancock County, Ohio, alleges in Craig Pingle v. Abraham, Watkins, Nichols, Agosto & Friend, et al. that he should have received a settlement totaling more than $436,000.
