In the law of Patents, the presence of two pending applications, or an existing patent and a pending application that encompass an identical invention or discovery.

When interference exists, the Patent and Trademark Office conducts an investigation to ascertain the priority of invention between the conflicting applications, or the application and the patent. A patent is customarily granted to the earlier invention.

In the meantime, the fluctuation of outputs goes smaller, which implies that the effects of microwave electromagnetic interference get suppressed at higher frequency and the susceptibility of CMOS RS flip-flops to microwave electromagnetic interference is inversely proportional to the frequency.
For instance, considering flip-flop 2, the states of MOS devices in flip-flop 2 are given typically as Table 2 before microwave electromagnetic interference turns on.
16 ns while the frequency of microwave electromagnetic interference is 1 GHz (flip-flop 2 changes its output state at 1 GHz as shown in Figure 6(a)) and 5 GHz (flip-flop 2 don't change its output state as shown in Figure 6(b)), respectively.
6] turns from "ON" state to "OFF" state gradually under microwave electromagnetic interference at 1 GHz.
In Figure 5(b), the output voltage under microwave electromagnetic interference could be divided into two stages.
It is clearly found that microwave electromagnetic interference with 5 V at 5 GHz is unable to switch the output state of flip-flop 1 as the pulse width is fixed at 2 ns, while the pulse width of 4 ns presents a similar result as shown in Figure 5(b).
Under such circumstances, the power of microwave electromagnetic interference pulse P is given by
It is found that the power of microwave electromagnetic interference is inversely proportional to the pulse width as stated above and 3 ns is determined to be so-called inflection point, which also verify the previous inference.
Further, the energy of microwave electromagnetic interference pulse E can be expressed from the power P
Simulated results of susceptibility of two categories of CMOS RS flip-flops to microwave electromagnetic interference have been reported.
