 Bell was in Boston on February 14 and did not know this had happened until he arrived in Washington on February 26.On February 19, Zenas Fisk Wilber, the patent examiner for both Bell's application and Gray's caveat, noticed that Bell's application claimed the same variable resistance feature described in Gray's caveat, and both described an invention for "transmitting vocal sounds".Wilber suspended Bell's application for 3 months to allow Gray to file a full patent application with a request for examination.
