Final answer:
CellTones should be most concerned about patent laws as it prepares to enter the market with its new products and services.
Step-by-step explanation:
CellTones, a new company selling several lines of cellular phones, should be most concerned about patent laws as it prepares to enter the market with its new products and services. Patent laws protect inventions and give the inventor exclusive rights to their creation. If CellTones closely modeled its products after successful products already in the marketplace, it may face legal issues if those products are protected by patents.
