Wheatstone was so cooperative, and Arthur naturally couldn't let him be disappointed; he smiled and reminded him,
"Speaking of which, Mr. Wheatstone, you haven't submitted a patent application to the Home Office yet, have you? Forgive my frankness, the principles of the phonograph aren't actually that complex, and if others figure it out, I'm afraid similar imitation products will appear very soon. Maybe you can establish your competitive advantage through technological upgrades, but seeking legal protection is also essential."
Upon hearing Arthur bring up the matter of the patent, Wheatstone could not help but sigh, "Of course, I know I need to apply for a patent, but even if the approval process for the patent is expedited, it would still take at least a year and a half. I haven't even completed the patent process for my previous device, the 'all sound conduit,' and it looks like the phonograph will have to wait its turn."
