In my AngularJS App, I have a form in which the user needs to enter an application number, and if successful, display content below which displays appropriate data. This data I can only access through the scope if I pass it as a parameter to the current state. I am using ui-router for routing. 
I have read threads such as Reloading current state - refresh data which has advised me that I can pass data to the current state and not refresh the page but it keeps refreshing and the content doesn't show. I am also not sure whether I am using ng-show and/or ng-if correctly. My function to pass the data is as follows:
vm.findPatent = function(patentNo) {
    searchPatentService.findPatent(patentNo)
    .then(
        function(data) {
            $state.go('.', { patent: data }, {reload: false, notify: false, location: false})
            })
        },
        function(errResponse) {
            console.error('Error while finding patent');
        }
    );
}
And my parameters within the state:
.state('search-patent', {
    url: '/search-patent',
    component: 'searchpatent',
    params: {
        navigation: 'patentnav',
        patent: null
    }
})
And my view with the form which displays the content below on form submit:
<form ng-submit="$ctrl.findPatent(searchPatent)" name="searchPatentForm">
    <fieldset>
        <div class="form-group row">
            <labelfor="searchPatent">EP No.</label>
            <div>
                <input type="text" name="searchPatent" ng-model="searchPatent" class="form-control" placeholder="Search" required>
            </div>
        <div>
            <button type="submit">Submit</button>
        </div>
    </div>
  </fieldset>
</form> 
<div class="row" ng-show="searchPatentForm.$submitted">
    <div class="col-md-12">
//ANOTHER FORM AND CONTENT WHICH IS DISPLAYED ON SUBMIT
    </div>
</div>
Question
How do I pass the data to the current state without refreshing the page? Also, is there a better solution to using ng-show? Thanks
