In past years, the author worked with patterns in prime numbers in different situations. It means, in terms of lengths, such as 10, 9, 8, 7 and 6. The prime patterns are understood as fixed digits repetitions along with prime number resulting again in a new prime number. These types of patterns are of fixed length. In this work, the prime patterns are written for the 4-digits prime numbers, i.e., . i.e., from 1009 to 9973. In this case there are total 1061 prime numbers. Most of the results are obtained for the prime patterns of length 7 up to 8 digits repetition of fixed digits. There are very few examples of length 8 and length 9. The work for the prime numbers up to 3-digits is recently done by author. The continuation of the same work for 5-digits prime numbers are under study. Moreover, the fixed repetition numbers are always multiples of 3.
