Derek Vandenburgh represented Tomato Land Display Systems, who was charged with infringing a patent related to anti-theft technology for audio and video cassettes and discs. Mr. Vandenburgh prevailed on a motion for summary judgment of non-infringement, avoiding trial on the dispute while fully exculpating his client of all allegations of wrongdoing. The case is reported at 92 F. Supp. 2d 733 (S.D. Ohio 2000).
